The Ultimate Guide to U.S. Security Clearances (2025)

Security clearances can seem mysterious and complex – especially if you’re new to the process. Whether you’re a civilian professional, a service member, a federal employee, or a contractor, understanding how U.S. security clearances work is crucial if your career involves sensitive government information. At National Security Law Firm, we’ve guided many clients through the clearance maze. In this beginner-friendly guide, our attorneys break down the most commonly asked questions about security clearances. You’ll learn what clearances are, why they exist, how to get one, how long it takes, what could disqualify you, and how to handle denials or renewals. We’ll also dispel some common myths along the way. Our goal is to provide a clear, authoritative roadmap – and if you need personalized help, our team is only a call away.

What Is a Security Clearance?

A security clearance is an official determination by the U.S. government that an individual is eligible to access classified national security information. In simple terms, it’s like a background check “badge” that says you can be trusted with secret information. The clearance itself is “eligibility for access” – it allows you to be considered for access to classified info up to a certain level, if you have a need to know that information for your job.

Security clearances come in levels (more on those below), corresponding to how sensitive the information is. They are granted only after a thorough background investigation and adjudication process confirming that you are trustworthy, reliable, and loyal to the United States. In essence, a clearance is the government’s way of saying, “We’ve checked this person out, and we trust them with our secrets.” It’s important to note that a clearance is a privilege, not a right – even once you have one, you must follow strict rules in handling classified materials, or you can lose it.

Why Do We Have Security Clearances? Security clearances exist to protect national security. Certain information – from military plans to intelligence sources – could cause damage, serious damage, or grave damage to U.S. security if it fell into the wrong hands. The clearance system ensures that only individuals who have been vetted for honesty, character, loyalty, and reliability are allowed such access. It’s designed to assess whether you are sufficiently trustworthy to keep secrets safe. In the words of the FBI, the background investigation “is designed to allow the government to assess whether a candidate is sufficiently trustworthy to be granted access to classified information,” checking criteria like honesty, financial responsibility, criminal history, mental health, and foreign associations. By screening for red flags (e.g. criminal behavior, ties to hostile foreign actors, serious financial duress), the clearance process helps mitigate the risk of espionage or unauthorized disclosures. In short, security clearances are required to ensure that those handling sensitive information will not put national interests at risk.

Levels of Security Clearance: Confidential, Secret, and Top Secret

The U.S. government uses three main levels of security clearances for national security information. Each level corresponds to the severity of damage that unauthorized disclosure of the information could cause to national security:

• Confidential: This is the lowest clearance level. It covers information that could cause damage to national security if improperly disclosed. Confidential clearances are less common nowadays and often held by support staff or military personnel in positions where only limited sensitive information is handled. Historically, a Confidential clearance required reinvestigation every 15 years (though this is changing with new continuous vetting – see below).

• Secret: This mid-tier clearance covers information that, if leaked, could cause serious damage to national security. Secret is one of the most common clearance levels; many military service members, law enforcement officers, and defense contractors hold Secret clearances. Obtaining a Secret clearance involves a moderate background investigation (covering roughly the past 5–10 years of your history). It traditionally required reinvestigation every 10 years. A Secret clearance allows access to information up to the “Secret” level, as well as “Confidential.” It does not allow access to Top Secret info.

• Top Secret (TS): This is the highest standard clearance level. Top Secret information is defined as that which could cause “exceptionally grave damage” to national security if revealed without authorization. A TS clearance is held by those in the most sensitive roles – high-ranking officials, intelligence officers, critical defense personnel, etc. Getting a Top Secret clearance involves a very extensive investigation, often looking back at your entire adult life. Investigators verify your citizenship, education, employment, finances, foreign contacts, and more, and conduct interviews with neighbors, employers, and references to build a complete picture of your trustworthiness. Top Secret clearances formerly required reinvestigation every 5 years.

In addition to these three levels, there are special designations for even more sensitive information:

• Sensitive Compartmented Information (SCI): This is not a separate clearance level, but an additional handling caveat for intelligence information. “SCI” refers to classified information derived from sensitive intelligence sources or methods. Access to SCI requires a Top Secret clearance plus a formal need-to-know approval for a specific “compartment” of information. Often, agencies like the CIA, NSA, or DIA will sponsor someone for “TS/SCI”, meaning Top Secret clearance with eligibility for SCI access. SCI programs frequently require polygraph examinations and additional background checks. In practical terms, being “read on” to SCI means you have clearance to see certain code-worded intel information that even other Top Secret-cleared personnel can’t see unless they have that same SCI authorization. The SCI designation is an add-on indicating compartmentalization, not a standalone clearance rank.

• Special Access Programs (SAP): These are another category of compartmentalized programs. A SAP is a program that restricts access to a particular extremely sensitive project or operation beyond normal classified handling. Examples might include cutting-edge weapons development or covert programs. Like SCI, a SAP clearance means you have additional “need-to-know” authorization. SAP access might come with its own code name and special background investigation requirements, strict nondisclosure agreements, and heightened ongoing monitoring. People sometimes refer informally to SCI/SAP as being “above Top Secret,” but technically they are Top Secret clearances with special access. You must first have a Top Secret clearance to be eligible for most SCI or SAP access. These special accesses are granted only to those with an absolute need-to-know and who meet extraordinary vetting standards (often including polygraphs and deeper scrutiny).

Need-to-Know Principle: Having a clearance doesn’t mean you can view any and all classified information at that level. Even among those with clearances, access is further restricted by “need-to-know.” You must have a specific, job-related reason to access a particular piece of classified info. For example, two people might both have Top Secret clearances, but if Person A has no need-to-know about Program X, they won’t be allowed to see Program X’s TS info. Special compartmented programs (SCI/SAP) formalize the need-to-know – you are only “read in” to the compartments your duties require. This prevents excessive sharing of secrets: even within cleared communities, information is shared only on a need-to-know basis.

Which Jobs Require a Security Clearance?

Security clearances are required for a wide range of jobs across the military, government, and private sector. Essentially, any position that will involve access to classified information or secured facilities will require the appropriate clearance. Here are some common categories of jobs and environments where clearances are needed:

• Federal Government Positions: Many roles in federal agencies require clearances. Obvious examples are in the Department of Defense (DoD) (e.g. working for the Army, Navy, Air Force, Marine Corps, or Space Force as a civilian or military member), the Intelligence Community (CIA, NSA, DIA, FBI, DHS intelligence, etc.), the Department of State (for diplomats and staff handling classified cables), the Department of Energy (certain nuclear or lab positions, using “L” or “Q” authorizations equivalent to Secret/Top Secret), and others like Department of Homeland Security, Department of Justice, etc. Even some roles in law enforcement or regulatory agencies can require clearances if they handle national security data.

• Military Service Members: Most military officers and enlisted personnel in sensitive fields will get a clearance. For example, nearly all commissioned officers are vetted for at least a Secret clearance, and many roles (intelligence, communications, special operations, nuclear fields, etc.) require Top Secret. If you join the U.S. Armed Forces and your job deals with classified info or equipment, the military will sponsor you for a clearance as part of your assignment. (Non-U.S. citizens cannot enlist in roles that need clearances, which is one reason U.S. citizenship is often a requirement for military enlistment in certain jobs.)

• Defense Contractors: Outside of direct government employees, a huge number of private sector contractors require clearances. Companies that contract with the DoD or intelligence agencies – think major defense firms like Northrop Grumman, Lockheed Martin, Boeing, Raytheon, Booz Allen, CACI, etc. – routinely hire engineers, IT professionals, analysts, and other specialists for projects that involve classified information or access to secure facilities. These contractors must have clearances commensurate with the project’s level (often Secret or Top Secret, sometimes with SCI or SAP). As Northrop Grumman notes, “the majority of jobs at Northrop Grumman require the individual to acquire and maintain a security clearance,” because they support classified U.S. government programs. In fact, DoD issues more than 80% of all security clearances (mostly to military and contractor personnel).

• Federal Contractors (non-Defense): Beyond defense, other federal domains also use cleared contractors. For instance, companies providing services to agencies like the FBI, CIA, NSA, DHS, or State Department often need cleared staff. Even some tech companies or consultancies have contracts involving classified work (e.g. cybersecurity for federal systems, intelligence analysis, etc.). If you’re working for a government contractor, your employer will tell you if a clearance is needed for the role and will sponsor the process.

• Law Enforcement and Local Officials: Typically, most state/local law enforcement do not need federal security clearances. However, those on federal task forces (e.g. Joint Terrorism Task Forces) or working closely with federal agencies might get sponsored for a Secret clearance to access federal intel. The FBI has a program to give state and local officials Secret or Top Secret clearances if needed for counterterrorism briefings. Similarly, certain emergency management or homeland security roles at the state level may require a clearance to interface with federal counterparts.

• Congressional Staff and Others: Members of Congress do not require clearances (by virtue of elected office they may access classified info), but some congressional staff who deal with classified info undergo background checks and effectively get clearances. Judicial branch officials or cleared attorneys may also require clearances for certain cases (e.g. handling classified evidence). These are less common but worth noting – essentially, wherever classified information goes, the people handling it must be cleared.

How many people have security clearances? It might surprise you, but millions of Americans hold security clearances. An annual report by the Office of the Director of National Intelligence (ODNI) found that as of 2019, approximately 2.9 million government employees and 1.3 million contractors/others held a clearance (Confidential, Secret, or Top Secret). That’s over 4.2 million cleared individuals. These numbers show that clearances are very common and span all levels of government and industry. Everyone from a Navy sailor with a Secret clearance, to an FBI agent with Top Secret, to a janitor at a sensitive facility with a Confidential clearance, to a software engineer at a defense firm with TS/SCI – all are part of the cleared workforce trusted to protect national security information.

How Do You Get a Security Clearance?

So, how does one actually get a security clearance? This is one of the most common questions we hear. Important: You cannot simply apply for a clearance on your own as a private citizen. There is a specific process:

1. Obtain a Sponsoring Employer or Agency: You must be sponsored by a U.S. government agency or a cleared contractor to start the clearance process. In practice, this means you first get a job offer (or military enlistment) for a position that requires a clearance. You cannot initiate a security clearance application by yourself as an individual – there’s no office where you can walk in and request a clearance for fun. As the State Department bluntly states: “Can I apply for a security clearance? No. Applicants cannot initiate a security clearance application on their own.” There must be a need for you to have access, usually in the form of a conditional job offer that is contingent on you obtaining the clearance. The hiring organization (your employer or the agency) will then file the necessary sponsorship paperwork to kick off your clearance investigation. (At National Security Law Firm, we even offer a pre-employment clearance screening service to help job seekers assess their “clearability” – more on that later – but even that doesn’t grant a clearance, it just helps you demonstrate suitability to potential employers.)

2. Complete the Security Clearance Application (SF-86): Once sponsored, you will be asked to fill out the Standard Form 86 (SF-86), Questionnaire for National Security Positions. This is a very comprehensive form – often 100+ pages when fully filled – covering your personal history. You’ll provide details on where you have lived, worked, and gone to school; your family members; any foreign contacts or travel; your financial records (debts, bankruptcies); your criminal history (if any arrests or charges); your past drug or alcohol use or counseling; your mental health treatment history; any organizational affiliations; and much more. Essentially, the government wants a full picture of your life to identify any potential security concerns. It’s critical to be thorough and truthful when completing the SF-86. Omitting required information or lying on this form is itself a serious issue (it’s a federal document) and can lead to clearance denial or even criminal charges if it’s a deliberate false statement. Pro tip: Take your time with the SF-86. Gather documents (addresses, contact info for references, etc.) in advance. Double-check dates and facts. If you have areas of concern (e.g. a past arrest or debt), you will still need to list them – better to proactively disclose and explain than to have investigators find out later. Honesty is paramount (we’ll discuss tips later). Remember, at this stage you’re essentially writing the first draft of your background investigation for the investigators to verify.

3. Background Investigation by DCSA (or Other Agency): After you submit your SF-86, the actual investigation begins. For the vast majority of clearance applicants (especially DoD and many other agencies), the Defense Counterintelligence and Security Agency (DCSA) will conduct the background investigation. DCSA handles clearance investigations for DoD and dozens of other federal departments as the central investigative service. In some cases, if you’re going to work for certain agencies (CIA, NSA, FBI, etc.), those agencies might run their own investigations or add additional checks like polygraphs. But the core process is similar.

• Checks Performed: Investigators will run criminal history checks (local, state, federal), credit checks (to see financial stability, debts), and verify key details you provided. They will obtain records like your birth certificate, school transcripts, military service records, and more for verification. For Secret clearances, the investigation (called a Tier 3 investigation) tends to focus on the past 5-7 years; for Top Secret (Tier 5), it’s often the past 10 years or more, and is much deeper. Investigators (who may be federal agents or contractor investigators) will also conduct interviews: typically, they interview you in person (a “subject interview”) especially for Top Secret or if any clarifications are needed for Secret, and they interview your references, employers, coworkers, neighbors, etc. For a Top Secret, expect that many people from your past – former bosses, roommates, references you listed, even ex-spouses or roommates – may get a polite knock on the door from an investigator. The investigator’s job is to verify your SF-86 info and dig up any issues. They might ask you in the interview about discrepancies or red flags (so you can explain them). In some high-security cases, a polygraph exam is required (common for SCI programs in intelligence agencies). A polygraph will cover topics like espionage, terrorism, truthfulness of your SF-86 answers, and in lifestyle polys, possibly questions about drug use or personal conduct. Not all clearances require a polygraph – it’s mostly for certain CIA, NSA, DIA, and SAP positions or certain law enforcement roles.

• Timeline for Investigation: The length of the investigation phase can range widely. Simple Secret clearance cases (for someone with a short, clean record) might be done in a couple months, whereas complex Top Secret cases can take many months. The FBI has stated a goal of 45 to 60 days for Secret clearances and 6 to 9 months for Top Secret after the submission of a completed application. In practice, government-wide averages have often been higher. For example, in FY2019 the average end-to-end processing time for the fastest 90% of cases was 125 days for Secret (~4 months) and 172 days for Top Secret (~5.7 months) – exceeding the desired timelines. Backlogs in recent years have caused waits of 6-12 months for many TS clearances. The good news is that the clearance system has been undergoing reforms to speed things up, and those average times have been improving. Still, as an applicant you should be prepared for a potentially lengthy wait, especially for Top Secret. Factors that can slow your investigation include extensive foreign contacts or travel, having lived in many different places (each needs to be checked), needing a polygraph scheduling, or any significant issue that requires extra digging. We’ll talk later about interim clearances, which can sometimes let you start work earlier.

4. Adjudication – The Clearance Decision: Once the investigation is complete, the gathered information is sent to a team of adjudicators. Adjudication is the process where a government official (the adjudicator) reviews your whole file and decides whether to grant you clearance eligibility or not. The adjudicator uses a set of 13 Adjudicative Guidelines – established by federal directive – to evaluate any security risks in your case. These guidelines cover areas like allegiance to the US, foreign influence, financial responsibility, criminal conduct, drug/alcohol use, mental health, personal conduct (honesty), and more (we’ll detail these in the next section). The adjudicator looks at the “whole person” – weighing any potentially negative information against positive factors and mitigation. For example, if you had a past issue (say, a DUI 5 years ago or some credit card debts), they will consider how serious it was, how long ago, and whether you’ve taken steps to address it. Mitigation is critical: evidence that problems are resolved or won’t recur can outweigh the concern. Adjudicators are trained to consider not just red flags, but also the context and your honesty about them. If everything in your investigation is fine, your clearance will be granted favorably. If there are concerns, the adjudicator might issue a “Letter of Intent” to deny along with a Statement of Reasons (SOR) outlining the issues – effectively an initial denial – giving you a chance to respond or appeal (see the section on denials/appeals).

• Interim Clearance: In some cases, while the full investigation is ongoing (especially if it’s a lengthy Top Secret investigation), the sponsoring agency may grant an interim clearance to allow you to begin work. An interim Secret is fairly common if your initial record checks show no problems – it could be granted within a few weeks after you submit your SF-86, pending the full investigation. Interim Top Secret is less common and SCI/SAP interim access is very rare. Note that if you lied or omitted important information on your forms, you will almost certainly not get an interim clearance. Interims are discretionary and only given when the early checks are clean. If an interim is denied, you simply have to wait for the final clearance decision. An interim denial doesn’t mean you’re doomed; it might just mean the agency prefers to see the complete investigation first. But it can be a hint that something in your record raised a question early on. Bottom line: be truthful and thorough on your forms – lack of candor is itself a red flag that can sink both an interim and final clearance.

If adjudication results in a favorable decision, you are granted a clearance at the required level. You’ll typically be briefed by a security officer on your responsibilities for protecting classified info and sign a non-disclosure agreement acknowledging the laws and penalties for leaking secrets. Congratulations – you are now “cleared”! If the decision is unfavorable (denial or revocation), you will be notified in writing and given the reasons and instructions on how to appeal or respond. We’ll cover that process later, as it’s important to know you do have recourse.

Key point: As an individual, you do not own a clearance; it’s tied to your need-to-know and sponsorship. If you leave the job or no longer require access, your clearance can be administratively withdrawn or rendered inactive. Think of clearance as “eligibility” – you have clearance eligibility up to a certain level, which can transfer with you to a new job if that job requires it (this is called clearance reciprocity). We’ll touch on transfers and keeping your clearance active in a later section.

Who Is Eligible for a Security Clearance?

Not everyone is eligible to obtain a security clearance. The government imposes some baseline requirements and carefully screens applicants for suitability. Here’s what you need to know about eligibility and potential disqualifiers:

• U.S. Citizenship: In nearly all cases, you must be a United States citizen to be granted a security clearance. The federal government generally will not clear non-U.S. citizens. There are extremely rare exceptions: for example, a non-U.S. citizen working on a specific allied contract might get a Limited Access Authorization (LAA) that allows limited Secret-level access for that project. But an LAA is not the same as a full clearance and does not confer broad eligibility. For practical purposes, assume you need to be a U.S. citizen (natural-born or naturalized) to pursue any cleared job. Dual citizens are eligible for clearances, but having a second citizenship can complicate the process (more on that under disqualifiers).

• Need for Access / Position Requirement: As discussed, you must have a legitimate job-related need. This isn’t a qualification you personally fulfill, but rather your job role must justify a clearance. No one gets a clearance “for personal use” or preemptively without a job. If you’re job hunting, you might see postings saying “must be able to obtain a Secret clearance” – that implies if hired, the company will initiate the clearance process. Occasionally, someone who already has an active clearance (from prior service or employment) has an edge in hiring because they can be “read in” faster. But if you don’t have one, employers can still hire you and sponsor you, as long as you meet the criteria.

• Trustworthiness and Character: This is broad, but essentially you must demonstrate good character, honesty, fidelity to the U.S., and overall reliability. The adjudicative guidelines used by the government spell out specific areas of concern (listed below). Adjudicators will evaluate your whole person against those. This process is not designed to select perfect people, but rather those people that exhibit high standards of honesty and integrity. In practice, this means you can have made mistakes in life (many cleared people have minor blemishes in their past), but you must be transparent about them and show that you’ve learned/overcome them. Honesty is absolutely essential. If you try to hide something, that lack of candor can sink you faster than the issue itself. Conversely, if you disclose an issue and mitigate it, you often can still get cleared. The investigators and adjudicators will verify if you meet the standards of loyalty, reliability, trustworthiness, discretion, and sound judgment needed for national security work.

Common Disqualifying Factors: Under the 13 adjudicative guidelines (A through M), there are certain red flags that can potentially disqualify an applicant. Some are absolute bars (cannot be waived), while others are situations that raise concern but can sometimes be mitigated. Here are the major categories:

• Allegiance to the United States (Guideline A): Any indication that you are not loyal to the U.S. – for example, advocating overthrow of the government, associating with terrorists or hostile intelligence services – is obviously disqualifying. (This is rarely an issue for most applicants, but it’s there.)

• Foreign Influence (Guideline B) and Foreign Preference (Guideline C): These relate to your ties to other countries. Having immediate family members or deep financial ties overseas, or exercising benefits of foreign citizenship (like using a foreign passport), can raise questions about divided loyalties. Dual citizenship itself is not an automatic disqualifier, but if you hold a foreign passport or are actively loyal to another country, it’s a problem. Mitigations include renouncing foreign citizenship or passports, showing that your family abroad poses no security risk, etc. Many clearance holders have foreign relatives – you just have to show you are aware of security responsibilities and firmly loyal to the U.S. (For instance, having an elderly parent in another country whom you visit isn’t grounds for denial by itself; but having a sibling working for a foreign military could be a serious issue.)

• Sexual Behavior (Guideline D): This is typically only a concern if it’s criminal or exploitable behavior. Consensual adult sexual conduct is not an issue for clearance unless it makes you vulnerable to coercion or involves crimes.

• Personal Conduct (Guideline E): This is a big one – it covers integrity, honesty, and general conduct. Lying on forms or to investigators, refusing to provide information, or a pattern of rule-breaking can fall here. One of the most common clearance denial reasons is “lack of candor” – e.g. concealing drug use or criminal behavior on the SF-86. Also, being fired for misconduct or other dishonorable behavior can show personal conduct issues. Bottom line: always be truthful and cooperative. If you mess up (e.g. forgot to list something), correct it quickly – adjudicators do consider self-correction as positive. The government defines personal conduct concerns as any conduct involving “questionable judgment, untrustworthiness, unreliability, or unwillingness to comply with rules.” Mitigating it often comes down to demonstrating you have reformed and that you’re now upfront and rule-abiding.

• Financial Considerations (Guideline F): Financial problems are a very common issue. Significant unpaid debt, a history of bankruptcies or evictions, failure to pay taxes, or anything suggesting you can’t meet financial obligations can indicate unreliability or, worse, vulnerability to bribery. The government worries someone deep in debt might sell secrets for money. Not every debt is disqualifying; it depends on severity and what you’re doing about it. For example, a credit card that went to collections but you’re paying it off could be mitigated. But financial irresponsibility (multiple unpaid debts, unreported income, etc.) is taken seriously. It’s important to proactively resolve debts or set up payment plans if you can – and definitely disclose them. Gambling issues leading to financial ruin can also be disqualifying.

• Alcohol Consumption (Guideline G) & Drug Involvement (Guideline H): Substance abuse is another frequent clearance killer. The government has a longstanding zero tolerance for illegal drug use while holding a clearance. Even marijuana, despite being legal in many states, is illegal federally – using it can jeopardize a clearance (and indeed many federal employees and military have been denied or lost clearances for using state-legal marijuana). If you’re currently using illegal drugs, you will not get cleared. Period. Past drug use is not necessarily an automatic disqualifier if it was experimental or long ago and you clearly stop and intend never to use again. Many young applicants have some past use; adjudicators look at how recent, how frequent, and circumstances. Full disclosure and evidence of abstinence are key to mitigation. For alcohol, habitual excessive drinking that leads to criminal incidents (DUI, public intoxication) or shows lack of control can be a concern. If you have alcohol-related offenses or treatment, they will examine if you’re reformed. Demonstrating responsible use or recovery can mitigate this.

• Psychological Conditions (Guideline I): Having a mental health condition is not an automatic disqualifier – in fact seeking therapy is often viewed positively. The concern is if a condition affects judgment or reliability (for example, untreated severe illness that causes erratic behavior). If you have a condition that’s well-managed (medication, therapy) and are stable, it’s usually fine. However, if you’ve been declared mentally incompetent by a court or recently hospitalized for severe issues, they will require evidence of stability before clearing. Importantly, routine counseling (like for stress, depression, marital issues) is not going to hurt your clearance; the government explicitly encourages professionals to seek help and doesn’t want to discourage that.

• Criminal Conduct (Guideline J): Any serious criminal behavior will raise doubts. Felony convictions, espionage, violent crimes – obvious no-gos. But even a pattern of misdemeanor offenses can be an issue if it suggests unreliability. That said, a single minor offense years ago (e.g. a youthful indiscretion) can often be mitigated by time and clean behavior since. The key is disclosure and showing it was an isolated mistake. If you are on probation or pending criminal charges, you likely won’t get cleared until that’s resolved and some time has passed with demonstrated reform. A dishonorable discharge from the military is specifically listed as disqualifying for a clearance.

• Handling Protected Information (Guideline K): This pertains to security violations – e.g. if you have a history of mishandling classified or sensitive information. If you’re applying for your first clearance, this usually doesn’t apply (you haven’t had access before). But if you previously had a clearance and it was revoked for security breaches, that’s a big problem. It’s listed: if you’ve had a clearance revoked for security reasons, that’s disqualifying. Also, if you’ve ever been caught misusing classified info or IT systems (Guideline M), expect scrutiny.

• Other Guidelines: Outside Activities (Guideline L) covers any employment or activities that might conflict with security obligations (e.g. serving in a foreign military or political organization). Use of IT Systems (Guideline M) looks at misuse of computer systems (like unauthorized access, hacking) which might indicate you wouldn’t safeguard sensitive data.

That’s a lot to digest, but remember: having some issues in your background doesn’t automatically disqualify you. The adjudication process weighs mitigating factors: How long ago did it happen? Was it a one-time mistake or a pattern? Were there extenuating circumstances? Have you shown positive change? For example, a poor credit history or past bankruptcy will not necessarily disqualify you – but you’ll need to show you’re resolving your debts and that there’s no ongoing financial irresponsibility. Likewise, admitting to past drug use won’t automatically bar you if it was an isolated incident, not recent, and you’re abstaining now. Adjudicators are instructed that adverse information does not automatically result in denial – they consider the “whole person” and any mitigating conditions. They’re also instructed to consider the recency and seriousness of issues and if you’ve demonstrated reform. For example, having foreign relatives is a potential concern under foreign influence, but if those contacts are casual and result from official U.S. activities or your family circumstances, that can be mitigated. Ultimately, you need to be candid about any issues and ideally address them proactively. Many clearance applicants have some concerns in one or two areas yet still get cleared because they were honest and showed mitigating evidence.

Ineligibility: However, some things will pretty much stop a clearance in its tracks. Non-U.S. citizenship (except for an LAA scenario) = ineligible. Current illegal drug use = ineligible until you stop and demonstrate you’re done. Ongoing association with hostile foreign actors or terrorist groups = ineligible. Deliberate falsification of your clearance forms or intentional security violations = likely denial. If you have a dishonorable discharge or were fired for serious misconduct, expect it to be a significant hurdle. The adjudicative guidelines are public (Security Executive Agent Directive 4) if you want to see all the detailed conditions and mitigating factors for each. But in summary, the government wants people who are loyal to the U.S., honest, law-abiding, financially stable, free of substance abuse, and reliable in following rules and protecting information. If that sounds like you (or you can get yourself to that point), you have a good shot at clearance eligibility.

Tips for a Smooth Security Clearance Process

Getting a clearance can be stressful, but there are steps you can take to improve your chances of success. Here are some tips from our National Security Law Firm attorneys, based on years of experience helping clients with clearance issues:

● Be Thorough and Truthful on Your SF-86: This bears repeating because it’s the #1 advice. When filling out the clearance application, double-check every answer. Don’t leave blanks (unless instructed) and don’t guess at dates or details – get the accurate info. Disclose everything asked for, even if it’s embarrassing. Remember, hiding something is worse than the thing itself. Investigators have many tools and databases; chances are they will discover omissions. Lying or concealing info is itself a disqualifier under Personal Conduct (Guideline E) and even a potential felony (making false statements). If there’s something you’re tempted not to mention because it might look bad – that is exactly the thing you must mention. You will get a chance to explain it. As the clearance adjudication guidelines say, adverse information isn’t an automatic disqualifier and can be mitigated. But if you’re caught hiding it, adjudicators will assume you intended to deceive, which severely damages your trustworthiness. So, err on the side of full disclosure. For instance, if you used marijuana a few times in college, list it and the dates honestly – many applicants with similar histories still get cleared after explaining. But if you deny it and a test or admission elsewhere shows otherwise, you’ll likely be denied for dishonesty. One of our mottos: Honesty, even if uncomfortable, gives you a chance to mitigate; dishonesty will almost certainly torpedo your clearance. (You can’t mitigate lying, except by a very long passage of time and contrition.)

● Prepare Documentation and Details: The SF-86 will ask for a lot of information (addresses, contact info for people, etc.). Prepare in advance by gathering your records. Pull a free credit report to see what debts you have. Collect addresses of places you lived, even temporarily. Contact old employers to get exact dates of employment if possible. The more complete and exact your form is, the smoother the investigation. If investigators have to chase down missing info, it can delay things. Also, if you have police records or court documents for any arrests or legal cases, get copies – you may need to provide them or at least have details ready.

● Be Ready to Explain and Mitigate Issues: Nearly everyone has at least one “iffy” thing – be it a speeding ticket, a bout of credit trouble, or a foreign relative. Think about the potential concerns in your background and how you will address them. For example: Did you have a past drug use? Be prepared to document that it was infrequent and that you have stopped (and intend to never use illegal drugs again – adjudicators will want to see a “demonstrated intent not to use in the future”). Did you struggle with debt? Maybe have a plan in place: are you now on a payment schedule, or did you clear the debt? Showing recent, concrete steps to fix financial issues (like paying off collections, settling delinquent accounts) can strongly mitigate the concern. If you have foreign contacts that will be noted, you should be ready to explain who they are and why those relationships don’t pose a loyalty risk. The key is to present yourself as low-risk: stable, responsible, and aware of security obligations. If possible, gather character references or performance reviews; while you typically don’t proactively submit those in an initial investigation, they can be useful if you need to respond to any SOR or clarify matters in an interview.

● Mind Your Online Presence: Increasingly, investigators may review your public social media and internet presence as part of the background check (they are permitted to look at publicly available info). Do an audit of your online footprint. Clean up any unprofessional or extremist content that’s publicly visible. Ensure your LinkedIn or resume doesn’t contain false information that contradicts your SF-86. If you find “digital dirt” (like an old embarrassing post or comment), consider deleting it or at least be prepared to address it if ever questioned. Also, set your privacy settings wisely – investigators won’t hack into private accounts, but if you leave things public, assume they will see it. In short: present a respectable, consistent image online that aligns with the trustworthy person you claim to be.

● Avoid New Troubles During the Process: While your clearance investigation is underway, live your life on the straight and narrow. This is not the time to rack up new credit card debt, get a DUI, or start texting that foreign diplomat you met on vacation. New issues that arise can derail an almost-complete investigation. People have had clearances denied because something new happened (like an arrest or a new financial problem) just before adjudication. So, be extra mindful: pay your bills on time, don’t use drugs, obey all laws, and if something does happen (say you get a speeding ticket or you’re a victim of identity theft impacting credit), inform your security officer promptly. Self-reporting issues is far better than them finding out later.

● Utilize Internal Support and Outside Expertise if Needed: If you’re filling out the SF-86 and are confused by a question or unsure what to put, you can ask your company’s Facility Security Officer (FSO) or agency security officer for guidance. They often can clarify how to handle tricky entries. Additionally, if you foresee major problems (maybe you have a past foreign association or legal issue that’s hard to explain), it can be wise to consult a security clearance attorney for SF-86 advice before you submit your form. An attorney (like those at our firm) can advise on how to present information accurately without volunteering unnecessary detail that isn’t asked. They can also help craft written explanations for any mitigating circumstances to include with your SF-86 or to have ready for investigators. While lawyers aren’t needed for all initial applications, if you have serious concerns (e.g. multiple DUI convictions, a past positive drug test, etc.), getting legal advice early can make a difference. And certainly, if you get a Statement of Reasons (SOR) indicating a possible denial, seeking legal counsel is highly recommended before you respond.

● Stay Organized and Responsive: Once your investigation is underway, be responsive to any communications. If an investigator reaches out to schedule an interview or requests additional info, promptly reply and accommodate them. Delays in scheduling interviews or providing documents can prolong the process. Keep a folder (physical or digital) with copies of your SF-86 and any documents you provided, so if a question arises you can quickly reference exactly what you submitted. It’s also a good idea to keep notes of your contacts (investigator names, dates) in case you need to follow up on the status later.

● Maintain a Strong Ethical Track Record: Even beyond the investigation, remember that getting the clearance is not the end – you must keep yourself “cleareance-worthy” continuously. Avoid behaviors that could jeopardize your clearance down the road. This includes obvious things like not committing crimes or abusing substances. But also more subtle things: for example, now that marijuana is legal in many places, it might be tempting – but as a clearance holder you still cannot use it. Follow the rules about foreign travel reporting, no unauthorized disclosure, etc. Showing a pattern of responsible behavior will make your periodic reinvestigations (or continuous vetting checks) a non-issue and you’ll sail through renewals.

In summary: honesty, proactivity, and diligence are your best friends in the clearance process. Most people who are denied clearances are not denied because they told the truth about a risky behavior – they’re denied because they lied, or because the issue was too recent/ongoing to mitigate. If you show that any past issues are firmly in the past and that you’re now a stable, reliable person, adjudicators are often willing to grant the clearance with the belief you’ll uphold your duty. And if you need personalized guidance or have a particularly complicated case, National Security Law Firm is here to help you navigate the process successfully.

What If You’re Denied a Clearance? – Clearance Denials and Appeals

Facing a security clearance denial or revocation can be scary, but it is not necessarily the end of the road. There are established procedures to appeal or rebut a clearance denial. Here’s what to expect and how to respond:

Initial Denial and Statement of Reasons (SOR): If the adjudicator is inclined to deny (or revoke, in the case of an existing clearance) your clearance, you will typically receive written notice. In the Department of Defense clearance system (which covers most contractors and many employees), this notice often comes as a “Letter of Intent to deny clearance” accompanied by a Statement of Reasons (SOR). The SOR details each issue or adjudicative guideline that led to the unfavorable decision. For example, it might say you’re being denied due to Guideline F (financial considerations) with specifics like “$10,000 in delinquent debt to XYZ Bank” and Guideline E (personal conduct) for “falsifying your SF-86 by failing to report the debt.” Some agencies might call it a Letter of Denial or similar, but the content – a list of reasons – is essentially the same. This is not a final, irreversible decision yet; think of it as an official warning that “we plan to deny you, unless you can refute or mitigate these concerns.” Along with the SOR, the letter will instruct you how to respond and the deadline (often 20–30 days). It also tells you how to request a copy of the investigative file, so you can see what evidence they relied on (you should request that file ASAP, through the indicated process, to prepare your rebuttal).

Your Right to Rebut and Request a Hearing: Upon receiving an SOR, you have the right to rebut the allegations in writing, and in many cases, the right to request a hearing to present your case in person. The specific procedures vary by your status:

• DoD Contractors: If you’re a defense contractor applicant, your case falls under the Defense Office of Hearings and Appeals (DOHA) process. You would submit a written Answer to the SOR – admitting or denying each listed allegation and providing explanations and any evidence to mitigate the concerns. In your answer, or separately, you can request a hearing in front of a DOHA Administrative Judge. At a hearing, you (and/or your attorney) can present witnesses, documents, and arguments on your behalf. You also have the right to cross-examine the government’s witness or challenge their evidence(often the government’s case is just the investigation file, presented by a Department Counsel attorney). Hearings are like mini-trials, though somewhat less formal. If you do not request a hearing, you can have the case decided on the written record – DOHA will send you a File of Relevant Material (FORM) which is basically the evidence being given to the judge, and you can respond to that with a written brief. Most applicants opt for a hearing if they strongly contest the issues, as it’s usually the best chance to personally demonstrate credibility and present mitigating facts. After the hearing or record review, the DOHA judge issues a written decision, and DOHA implements it (granting or denying clearance accordingly). If denied by the judge, you can appeal to the DOHA Appeal Board within 15 days, though appeals must point out specific legal or procedural errors, not just reargue the facts.

• Federal Civilian Employees and Military Personnel: If you’re a direct government employee or service member, the process is slightly different. Typically, you can submit a written rebuttal to the SOR within the agency’s allotted time. For many DoD civilian/military cases, you don’t automatically get a live hearing at the initial appeal stage; instead, the adjudication facility or a Personnel Security Appeals Board will review your written response and make a decision. If they still deny, you may then be offered an opportunity for a “Personal Appearance” before an adjudicator or administrative judge. A Personal Appearance is essentially a hearing where you can present your case verbally (it’s called “personal appearance” in some agency regulations, particularly for intelligence community appeals). The exact process depends on the agency’s regulations (for example, intelligence agencies have internal review panels; DoD civilians might get a DOHA administrative judge hearing as the personal appearance). The initial SOR letter should outline your specific appeal rights. Always exercise your right to provide a rebuttal – if you don’t respond at all, the denial will become final by default.

How to Craft an Effective Rebuttal: This is where a security clearance attorney’s guidance is especially valuable, but generally, your response to an SOR should include:

• Point-by-point refutation or mitigation: Address each listed concern. If something is factually incorrect, provide evidence (e.g., “The SOR says I have $10k debt to XYZ Bank. This is incorrect; I paid that debt in full in 2024 – see attached receipt.”). If the concern is true but mitigable, explain the mitigating factors (e.g., “I did have a DUI in 2021, but I have since completed an alcohol counseling program and have had a clean record for 4 years. Multiple character references attest that this was an isolated mistake.”). Cite any official guidance that helps (the Adjudicative Guidelines list circumstances that can mitigate each issue – use those terms if they apply, like “not recent,” “isolated incident,” “motivated by circumstances that no longer apply,” etc.). Show positive changes: for financial issues, demonstrate you’re resolving them (attach proof of payments or settlements); for drug issues, document negative drug tests or a statement of commitment to abstain.

• Whole-Person narrative: You want to convince the decision-maker that, despite the flagged issues, granting you clearance is clearly consistent with national security interests (the legal standard). Highlight your positive attributes: military service, public trust positions you’ve held, accolades, community involvement, etc., to show you are a responsible person. Emphasize your understanding of security obligations and, if relevant, remorse and rehabilitation for past mistakes. Essentially, you’re saying “I acknowledge these issues, but here’s why you can still trust me with classified information.” For example, if foreign influence is a concern (say you have family in another country), stress your deep loyalty to the U.S., maybe note that you immediately report all foreign contacts and would never let family ties override duty. If personal conduct (e.g. an omission) is an issue, own up to it and clarify that it was not malicious – maybe an oversight that you corrected, or caused by misunderstanding the question, and that you’ve learned from it.

• Evidence and attachments: Whenever possible, attach supporting documents: financial statements, updated credit reports, reference letters, completion certificates for counseling or training, etc. These lend credence to your mitigation claims. If you have an attorney, they might also prepare a legal brief citing prior clearance appeal decisions (DOHA decisions are published) where similar cases were mitigated – this can help argue consistency.

• Timeliness and format: Respond by the deadline in the instructions. Keep a professional tone – this is a formal submission to a quasi-judicial process. If you’re mailing it, send via certified mail or other trackable means (some processes allow email). If you need more time for good reason (e.g. waiting on a document), you can often request a short extension.

The Hearing: If you proceed to a hearing (DOHA or otherwise), it’s your chance to personally advocate. It’s wise to have an attorney represent you if possible, or at least to prepare you. In the hearing, you can testify on your own behalf, have supporting witnesses (perhaps a supervisor or mentor who can vouch for your character), and submit any additional exhibits. The government will have an attorney (for DOHA) or representatives who may question you. The Administrative Judge will likely ask you questions too. Be truthful and respectful; if you don’t know an answer, say so – do not guess or make excuses. If there were mistakes, acknowledge them and focus on how you’ve changed. Hearings typically last a few hours and often you get a decision a few weeks to a couple months later in writing.

Possible Outcomes: If you succeed in your rebuttal or at hearing, your clearance will be granted (or reinstated) and you can move forward with employment. If you lose the appeal, the clearance is denied/revoked and that agency will discontinue your processing. You will usually be barred from being reconsidered for a clearance for a certain period (often one year) unless new evidence emerges. For DoD cases, regulations say you can reapply or be sponsored again after 12 months from the final denial, assuming you have mitigated the issues. The idea is to give you time to fix problems (pay off debt, stay drug-free, etc.) and then try again with a fresh start. Note: a denial by one agency is typically visible to others (through a system of record). While security clearance denials are supposed to be honored by other agencies (reciprocity rules), in practice after the waiting period another agency or contractor can sponsor you and a new adjudication can take place – they will see the prior denial and you’ll have to address what’s changed. We’ve helped clients successfully get cleared on a second attempt by showing substantial improvements in their situation and behavior since the denial.

No Judicial Appeal: One thing to understand is that clearance decisions are considered an executive branch discretionary decision tied to national security, so they are generally not subject to judicial review. You cannot, for instance, sue in court to overturn a clearance denial on the merits (courts almost always dismiss such cases, deferring to the executive’s authority in security matters). The exception would be if you believe you were denied purely for a legally prohibited reason (like discrimination), but even then courts give agencies wide latitude on clearances. In short, the agency’s appeals process is your day in court, so use it fully.

If Denied – Future Steps: If after appeals you remain denied or revoked, focus on addressing the reasons and documenting your rehabilitation during the waiting period. For example, if drugs were the issue, maintain sobriety and perhaps do volunteer work or other positive activities. If finances, aggressively settle debts and show a clean payment history. You want a solid package of evidence that “I fixed what concerned you” for any future clearance attempt. It can also help to obtain a professional security clearance consultation (like with our firm) to assess your case and advise when you’re ready to reapply.

Don’t lose hope: Many people initially denied have later obtained clearances after some time or upon providing additional context. The key is to take clearance officials’ concerns seriously and treat it as an opportunity to prove oneself. If you find yourself in this situation, consider reaching out to legal professionals (such as National Security Law Firm) who specialize in clearance denials and appeals – we can often pinpoint the weaknesses in the government’s case or highlight mitigating information that you might not realize is important. Our attorneys have helped clients successfully overturn proposed denials by crafting compelling responses and representation at DOHA hearings. The appeals process exists to ensure that one mistake or misunderstanding doesn’t unnecessarily end a qualified person’s national security career. Use that process to your full advantage.

Maintaining Your Clearance: Renewals, Reinvestigations, and Continuous Vetting

Getting your clearance is a big accomplishment – but it’s not a one-and-done forever. Clearances must be maintained and periodically updated to ensure you remain eligible and no new issues have arisen. In recent years, the government has been overhauling the traditional periodic review system in favor of “continuous vetting.” Here’s what you need to know about keeping your clearance active and in good standing:

Periodic Reinvestigations (PRs): Traditionally, a cleared individual underwent a full background reinvestigation at set intervals: every 5 years for Top Secret, every 10 years for Secret, and every 15 years for Confidential. These follow-up investigations were similar to the initial one – you’d update an SF-86, and investigators would check what you’ve been up to since the last investigation. The idea was to catch any new problems (e.g. accumulated debt, arrests, new risky behavior) that developed over time. If a periodic reinvestigation turned up concerns, you could potentially lose your clearance if they weren’t mitigated. Conversely, if everything was fine, your clearance would simply continue (“renewed” for another period).

• Note: People often say “my clearance expired” after e.g. 5 years. Technically, a clearance is valid as long as you are in a position that requires it and you’ve met the reinvestigation requirements. If the time interval passes without a PR, your access may be suspended until updated, but if there’s backlog you might still be allowed to work under an extension. The better term is your investigation is out-of-date, rather than clearance “expired.” But practically, yes, you need updated investigations to keep it active.

• For decades, these periodic checks were the norm. However, this led to a cycle of huge backlogs – with millions of clearance holders, doing millions of 5/10-year reinvestigations became cumbersome. It also meant someone could develop a problem (say, start misusing drugs or build up big debts) right after their last PR and it might not be discovered for several years until the next one.

Continuous Evaluation / Continuous Vetting: To address these issues, the government has been implementing a system of Continuous Evaluation (CE), now more broadly called Continuous Vetting (CV). As of 2021, all DoD clearance holders (about 3.6 million people) were enrolled in continuous vetting, and other agencies are following suit under the “Trusted Workforce 2.0” initiative. Under continuous vetting, automated checks are run regularly (often daily or monthly) against cleared individuals’ records – for example, pulling credit reports, monitoring for arrest records, checking if someone’s name shows up on a watchlist or in public social media for concerning behavior. If an alert or “hit” comes up (like a new arrest or a big debt or bankruptcy filed), the security officials are notified in near real-time. This way, potential problems can be investigated immediately rather than waiting years. One real example: DCSA’s vetting program got an alert that a cleared individual had an arrest warrant for serious charges the day after the incident – something that would have taken much longer to discover under old methods.

• Replacement of PRs: Continuous vetting is replacing the periodic reinvestigation schedule. For instance, DoD announced that continuous vetting will eventually replace periodic reinvestigations, which were every 10 years for Secret and 5 years for Top Secret. In practical terms, this means if you hold a clearance, you’re being checked in the background on an ongoing basis. If nothing negative pops up, you may not have to do the old fingerprint-and-interview reinvestigation as frequently (or at all). However, agencies may still require periodic re-submission of SF-86 information or brief updates to ensure their data is current. And if continuous checks surface an issue, you might be contacted to provide explanation or could be flagged for a “triggered” investigation out-of-cycle.

• Self-Reporting: Even with continuous monitoring, clearance holders are required to self-report certain changes or incidents to their security officer. This includes things like: foreign travel (usually you must report trips overseas before or after going), close and continuing contact with foreign nationals, marriage to or cohabitation with a foreign citizen, any arrests or criminal charges, substance abuse incidents, financial problems like bankruptcy or wage garnishment, and mental health hospitalizations (except voluntary counseling). You’re also required to report if you suspect someone else of a security violation or if you yourself accidentally compromise classified info. These reports allow security officials to address issues proactively. Failing to self-report something significant (like getting arrested over a weekend and hiding it) can compound your problems if it’s later discovered via vetting – it becomes a personal conduct issue (dishonesty) on top of the underlying issue.

Keeping Your Clearance “Active”: A clearance is considered active as long as you are in a job that requires it and you have an up-to-date investigation per the guidelines (or are enrolled in continuous vetting). If you leave a cleared position (say you quit your job or are reassigned to duties not needing clearance), your clearance doesn’t immediately vanish, but it becomes “dormant” or “inactive.” Essentially, you still have eligibility for the clearance level for a period of time, but you have no current access. Typically, if you get another cleared job within two years, your clearance can be reactivated via reciprocity without a full new investigation. Agencies follow reciprocity rules which say a clearance “shall be accepted by other agencies” as long as it’s current. For example, if you left a DoD contractor job with a Secret clearance and 18 months later got a Secret-level job at DHS, DHS should generally honor your DoD clearance (they’ll verify it in the database) and not make you start over – though they might do some additional checks or require you to fill out a new SF-86 if your last investigation is close to out-of-date. If more than two years passes since you had access, your clearance is considered to have lapsed and you’ll likely need to go through a new investigation to restore it. Companies recruiting candidates with previous clearances often note “must have had a clearance within last 24 months” for an easier hiring process, because beyond that, reinvestigation is required from scratch.

Reinvestigation vs. Continuous Vetting Today: We are in a transition period. Many clearance holders under continuous vetting will no longer have the big 5-year or 10-year re-investigation; instead, they’ll just be monitored continuously and maybe asked to submit periodic updates. For example, DCSA’s continuous vetting program is at an interim stage where automated checks cover many data sources, and it’s incrementally being enhanced. Eventually, the vision is a “trust but verify constantly” model, dubbed Trusted Workforce 2.0, where issues are caught early and adjudicated as they arise, rather than waiting for a scheduled review. This should make the clearance process more dynamic and arguably more forgiving – if an issue pops up but is resolved, your record updates to reflect that resolution rather than compounding over years.

If You Already Have a Clearance: To maintain it, follow the rules and report what you’re supposed to. Take annual security refresher trainings seriously; they often update you on reporting requirements and new policies. When in doubt about whether to report something (e.g., you start dating someone from another country, or you get a notice of a federal tax lien), err on the side of reporting to your security officer. You won’t be punished for reporting – at most they’ll note it and perhaps ask follow-up questions, but it shows good faith. Not reporting, however, if discovered, will be viewed negatively.

Also, practice good OPSEC (operational security) and INFOSEC in your daily work – don’t be the person who gets a security violation for leaving a safe unlocked or connecting an unauthorized device to a classified network. While an inadvertent mistake might not cost you your clearance if it’s minor and no compromise occurred, a pattern of negligence could.

Finally, be mindful that clearance vetting now is a continuous 24/7 responsibility. Treat it akin to a credit score that’s always being checked – but instead of credit, it’s your life choices. This doesn’t mean you can’t live freely; it just means major issues will be noticed. Live by the standards you agreed to: stay law-abiding, stay solvent, remain loyal to your oath, and you should have no trouble keeping your clearance indefinitely.

Common Myths and FAQs about Security Clearances

There are plenty of misconceptions surrounding security clearances. Let’s tackle some frequently asked questions and common myths to set the record straight:

• Q: Can I apply for a security clearance on my own, even if I don’t have a job yet?
  A: No. You cannot self-apply for a clearance without a sponsoring employer or agency. Many people think there’s a central place to get “pre-cleared” to boost job prospects – but the government does not grant clearances just to individuals in general. You must have a conditional job offer or military position that requires clearance; then that employer will initiate the process for you. (Myth-buster:) Some private services advertise they can get you a clearance – be wary. What they might do is help evaluate if you’re likely to qualify (like a pre-screening). In fact, at National Security Law Firm we offer a Pre-Employment Security Clearance Screening to assess your background and provide a letter stating you appear “clearable,” which can help in job applications. But to actually obtain an active clearance, you need to be sponsored after you’re hired.

• Q: Do I have to be a U.S. citizen to get a clearance?
  A: Yes, almost always. Security clearances are generally only granted to U.S. citizens. If you hold dual citizenship, you can still be cleared (though you’ll likely be asked to renounce or refrain from using your foreign citizenship privileges, like foreign passports, as a condition). Non-U.S. citizens are not eligible for a clearance, with only very narrow exceptions like the Limited Access Authorization (LAA) for certain Secret-level projects. For example, if a NATO partner country’s citizen is working in a U.S. contractor facility on a NATO program, they might get an LAA limited to that info – but it’s not a full clearance and does not allow broader U.S. classified access. So, for all practical purposes, you must be a U.S. citizen. (Note: A naturalized U.S. citizen is treated the same as someone born in the U.S. – being naturalized does not hurt your chances.)

• Q: If I have a criminal record or a history of drug use, am I automatically disqualified from ever getting a clearance?
  A: Not necessarily. It depends on the severity, recency, and your conduct since. Felony convictions or imprisonment can be major hurdles – especially anything involving national security crimes or dishonesty. But many people with minor offenses or past drug experimentation have obtained clearances after showing they reformed. For instance, a one-time drug possession charge from college, or a DUI from several years ago, can often be mitigated with time and evidence of changed behavior (like no repeat incidents, rehabilitation). The adjudicative guidelines specifically allow consideration of mitigating factors such as the passage of time, the infrequency of conduct, and evidence of rehabilitation. Honesty is crucial: you must disclose these issues on your SF-86. If you try to hide them, a minor issue becomes a major integrity issue. A “poor credit history or other issues will not necessarily disqualify a candidate” either, as the FBI notes, unless they are significant and unresolved. Each case is unique, but there is a path forward for many individuals with past mistakes – often after a period of demonstrating reliability (usually the guideline: 12 months to a few years of no repeat problems is a good start). However, some things are essentially show-stoppers: ongoing drug use, a recent serious crime, a dishonorable military discharge, active alcohol abuse with no treatment – those will likely result in denial until you can show a change.

• Q: Will they interview my family, neighbors, and employer? This makes me nervous…
  A: For a Secret clearance, the investigation relies mostly on database checks and perhaps some reference verifications; you might not notice much beyond filling the form and maybe one interview. But for a Top Secret clearance, yes, it’s standard that investigators will conduct field interviews with people who know you. They may talk to your current and former supervisors, references you listed, and even some people you didn’t list (like neighbors or acquaintances identified during the investigation). They may also reach out to ex-spouses or ex-roommates (particularly anyone you were close to in the last 10 years). This is normal – don’t panic. The investigators are trained not to divulge unnecessary details; they usually just ask others about your character and whether they’ve observed any issues (drug abuse, strange foreign contacts, etc.). Most people will just say positive or neutral things. It’s relatively rare for investigators to dig deeply into extended family unless needed for a specific reason. Understandably it can feel invasive, but it’s part of the rigorous process for TS clearances. If you anticipate a certain person might not speak well of you (maybe a bitter ex-friend), you can mention that during your subject interview to give context – adjudicators weigh grudges and bias if evident.

• Q: What about my privacy? Will they look at my medical records or polygraph me about personal matters?
  A: Medical records: For most applicants, your medical history remains private except the mental health questions on SF-86 (which ask if in the last 7 years you had certain issues or hospitalizations). Even then, simply seeking mental health counseling for things like depression, grief, or family issues is not disqualifying and you can even have your therapist provide a letter that your condition doesn’t affect judgment. They won’t request medical records unless there is a security-relevant concern (e.g., evidence of an untreated serious mental illness or substance abuse). Polygraphs: Only certain agencies/positions require them (CIA, NSA, DIA, certain DoD units, etc.). Polygraphs typically focus on specific topics: involvement with espionage, terrorism, illegal drug use, serious crimes, and truthfulness of your SF-86 responses. There are also lifestyle polygraphs in some cases that ask about general personal behavior (drug habits, sexual behavior only if it could be used for coercion, etc.). They do not ask irrelevant personal questions without a security purpose – e.g., they’re not interested in your private political opinions or intimate life unless it intersects with a guideline (like a hidden affair that could be used to blackmail you, perhaps). A polygraph can be stressful, but remember it’s just one tool – failing one doesn’t automatically mean clearance denial; agencies often give additional polys or weigh the results with other info.

• Q: My friend has a Top Secret clearance. Can they tell me what they work on?
  A: No, not if it’s classified. And you shouldn’t ask for details. “Need-to-know” applies even among cleared individuals. If you don’t have a clearance (or don’t have the same level and need-to-know), your friend is legally and contractually bound not to share classified information with you. Clearing someone isn’t permission to spill all secrets – it’s granting them access only to what they specifically need for their role. Also, many cleared projects are sensitive enough that even saying you work on them can be off-limits. For example, someone with a TS/SCI clearance at NSA can’t come home and tell family, “I read intercepted communications of foreign leaders today” – that itself is classified. It’s best not to pressure friends or relatives to divulge things; cleared folks are trained to politely decline such discussion. As a citizen, the existence of classification means some stuff you just won’t know unless/until it’s declassified publicly.

• Q: Is a security clearance like a credit score that I carry with me? How long does it last?
  A: A clearance is held by the government, not you, but it is portable in the sense that if you switch jobs to another cleared employer, the new employer can usually have your clearance transferred/reciprocated without a full redo. However, transfers between agencies can sometimes face bureaucratic delays or additional checks – e.g. an FBI clearance might transfer to DoD, but DoD might still do a polygraph if they require one whereas FBI didn’t. By policy, “all security clearance background investigations and determinations completed by an authorized investigative agency or adjudication agency shall be accepted by all agencies” (that’s from a 2004 law on reciprocity), meaning if you’re cleared by one, another shouldn’t make you start over. Limited exceptions exist for especially sensitive programs or if your investigation is out-of-date. In terms of duration: as long as you’re in a clearance-required position and comply with reinvestigations or continuous vetting, your clearance has no set expiration. If you leave a cleared role, your clearance will terminate or become inactive – typically after 24 months of not being in access, it expires and you’d need a new investigation to get it back. Practically, think of a clearance as valid for up to two years after leaving a job, after which you can’t assume you “have” it anymore. Always keep records of your clearance dates; if you are job hunting, prospective employers will ask when your last investigation was and when you last held clearance. If it’s beyond the two-year mark, they know they’ll have to sponsor a fresh check.

• Q: Can I lose my clearance once I have it? What are common reasons clearances get revoked?
  A: Yes, maintaining a clearance means you must continue to uphold the standards. Clearances can be suspended or revoked if new issues come to light. Some common reasons for clearance revocations are:

  • Drug use while holding clearance: If you decide to start smoking marijuana or using any illegal drug after getting cleared, you’re very likely to lose your clearance (and your job) if it’s discovered. As noted, state legality doesn’t matter – it’s illegal federally and against clearance rules.

  • Serious financial problems or unexplained affluence: If you accumulate large, delinquent debts or suddenly can’t account for an influx of money, security officials worry about vulnerability to bribery or that you’re selling secrets. Failure to file taxes or big gambling losses have triggered revocations.

  • Criminal conduct or security violations: An arrest for a serious offense (e.g. assault, DUI if frequent) can jeopardize clearance. Mishandling classified info (bringing it home, emailing it on personal account, etc.) can lead to clearance suspension pending an investigation, and potentially revocation if it was willful or grossly negligent.

  • Unauthorized foreign contacts: If you begin associating with foreign intelligence or don’t report close foreign relationships, you could be seen as a security risk.

  • Lying during a reinvestigation or polygraph: Just as during initial vetting, dishonesty later can result in clearance loss. If during a periodic check you conceal something and they catch it, you might lose clearance for personal conduct.

  That said, revocations aren’t arbitrary. You would typically be confronted with the issue (via an SOR in the revocation context) and given a chance to respond, similar to an initial denial. According to one law firm’s data, the top reasons for clearance denial or revocation in recent years include drug involvement, personal conduct (often falsification), financial issues, and foreign influence. If you avoid those pitfalls and promptly address any personal problems, you greatly reduce the chance of ever losing your clearance. Remember, a clearance is a privilege conditioned on your continued adherence to rules and demonstration of trustworthiness.

• Q: I heard about “continuous monitoring” – does that mean they’re watching everything I do?
  A: Not exactly – they’re not following you with a surveillance van or reading your private emails (unless of course you’re under a specific counterintelligence investigation, which is not routine for most). Continuous Vetting means the government is regularly checking certain data feeds for red flags. For example, they will pull automated updates on your credit report, criminal record databases, and maybe public social media or civil records.They also get alerts if say your name hits an FBI arrest entry or if you’re listed in a financial fraud report. It’s somewhat like how credit monitoring works for identity theft – a ping goes off if something changes. If you’re living a normal, law-abiding life, these checks will be invisible to you. If something does pop (e.g., you default on a loan or get sued or arrested), your security office may quietly follow up to see if it’s a concern. You might be contacted to provide information or an interview if needed. It’s important to know that as a clearance holder you have consented to this ongoing monitoring. But it’s not Big Brother reading your diary – it’s targeted at security-relevant information.

• Q: If I change jobs or move to a different agency, will I have to start my clearance all over again?
  A: In general, clearance transfers (reciprocity) are straightforward. If you already have a clearance at the required level, a new employer (or agency) can usually verify it in the Joint Personnel Adjudication System (JPAS) or successor system (DISS/NBIS) and transfer your eligibility without a full re-investigation. This saves time and money. However, there are a few caveats:

  • Polygraphs and Special Access: If your new position requires a polygraph and your old one didn’t, you might need to undergo that (but you wouldn’t redo the whole background check, just the poly). Similarly, SCI access might not auto-transfer if it’s a different compartment – you may need separate read-in approval.

  • Out-of-scope Investigations: If your investigation is older than the allowed interval (e.g. more than 5 years for TS and you haven’t been in continuous vetting), the new agency might require you to update your SF-86 and submit to a new investigation before giving you access. They may allow you to start work if non-cleared duties exist, but classified access might wait for the update.

  • Some Agency Idiosyncrasies: Historically, a few agencies like CIA or DOE sometimes re-adjudicated cases in their own way. Nowadays, by policy they should accept existing clearances (“all security clearance determinations by an authorized agency should be accepted by all agencies” – Intelligence Reform Act), but they may still do an additional suitability check or polygraph. One ClearanceJobs forum anecdote noted a DoD-cleared person had to still fill forms for a DOE clearance because DOE calls theirs “Q” clearance – but those are essentially equivalent. In any case, you usually do not have to start from scratch unless you had a long break in service or a major change in circumstance.

  In summary, if you already have a clearance, leverage that. Let your new employer’s security office know early, provide any documents (e.g. clearance verification letter or SF-86C update) they ask for, and the process should be much quicker than the first time.

• Q: How do I check the status of my clearance application?
  A: The clearance process can feel like a black box. Unfortunately, as an applicant you have limited insight. Your employer’s security officer can check the investigation status in the system (e.g. whether it’s pending, closed, or adjudication in progress). You generally can’t directly call OPM or DCSA as an applicant for updates – they’ll refer you to your FSO. If it’s been a long time (many months) and you’ve heard nothing, you can ask your recruiter or security officer to inquire. Sometimes clearances seem stuck simply due to backlog. There is also an electronic “Check My Clearance” portal for some applicants (DCSA was developing one), and certain agencies give you login info to check status updates (the Intelligence Community’s applicant portals often show where you are in the process). But absent that, patience is key. If extremely delayed, an option is to contact your congressional representative – they can in some cases inquire on your behalf if a background investigation is significantly overdue (this is rare but has happened when backlogs were huge).

• Q: Can I discuss my clearance level or the fact that I have a clearance?
  A: Generally, saying you have a Confidential/Secret/Top Secret clearance is not classified – it’s common on resumes and LinkedIn for cleared professionals to mention their clearance level as a qualification. The government even publishes aggregate numbers of clearance holders. However, details beyond that can be sensitive. You should never reveal specifics of special access (SCI/SAP) you have in public. For instance, don’t post “I have a TS/SCI with XYZ compartments and codewords” – that’s too much. Also be cautious about discussing clearance-related matters with uncleared friends. There’s also personal OPSEC: broadcasting that you have a high-level clearance could potentially make you a target for foreign intelligence social engineering. It’s okay to say “I hold a Top Secret clearance” in job contexts – that’s expected – but you don’t need to advertise it to the world on Facebook. And absolutely do not share any classified project names or details you learned via your clearance. A good rule is: it’s fine to mention your level (and polygraph status) when job-hunting or networking in cleared circles, but remain discreet about everything else.

These FAQs address some of the most common points of confusion. If you have a question that wasn’t covered, chances are the answer boils down to one of the fundamental principles we’ve discussed: citizenship, trustworthiness, need-to-know, and honesty. When in doubt, consult with your security officer or legal counsel for guidance specific to your situation.

Navigating the Clearance Process with Confidence

Security clearances are the gatekeepers to some of the nation’s most sensitive secrets. By now, you should have a solid understanding of what clearances are, why they exist, the different levels and special accesses, how to obtain one, and how to keep one. We’ve walked through the step-by-step process – from application to investigation to adjudication – and shed light on the criteria that adjudicators use to judge your worthiness for access. We’ve also busted some myths and answered key questions that often puzzle first-timers. The overarching theme is clear: a security clearance isn’t about being perfect; it’s about being honest, responsible, and loyal in a consistent manner.

If you’re just beginning your journey toward a clearance-requiring career, don’t be intimidated. Millions have gone before you, and while the process can be lengthy and detailed, it’s manageable with preparation and integrity. Use the tips we provided: start by keeping good records, cleaning up any personal issues you can, and always err on the side of disclosure and forthrightness. If you run into bumps – like receiving a Statement of Reasons for a potential denial – remember that you have the right to appeal and explain your case, and many people do successfully overturn initial denials. The key is addressing the concerns head-on with facts and mitigation.

One more thing: securing a clearance can open doors to rewarding careers in government, military, and contracting. It’s almost like a passport to a whole ecosystem of jobs labeled “cleared.” Treat that “passport” with care. Once you have a clearance, safeguard it by living up to the trust placed in you – follow security procedures diligently, stay out of legal/financial trouble, and report what you’re supposed to report. Think of yourself as a member of a trusted community – because you are.

Finally, if you ever feel unsure at any stage – whether filling out your SF-86, responding to an investigator’s questions, or dealing with an SOR – know that you don’t have to navigate it alone. At National Security Law Firm, this is what we do day in and day out: help individuals like you successfully obtain, defend, and retain their security clearances.

Why National Security Law Firm Handles Security Clearance Cases Differently

Security clearance decisions are made inside a federal system that values consistency, credibility, and record integrity over storytelling or advocacy flair. National Security Law Firm is built specifically to operate inside that system.

True insiders: former judges, adjudicators, and government decision-makers
Our team includes former judges, adjudicators, and attorneys with direct experience inside the Defense Office of Hearings and Appeals (DOHA) and other government clearance decision environments. We understand how credibility is assessed, how mitigation is weighed, and how risk is evaluated because we have participated in security clearance decisions from the government’s side of the table.

Federal Systems Defense™
Security clearance issues do not stay confined to the clearance process. They intersect with federal employment actions, investigations, criminal or quasi-criminal exposure, future reviews, and long-term career consequences. Our Federal Systems Defense™ approach treats your clearance case as part of a larger government system, not a standalone event.

Attorney Review Board (team-based case design)
Clearance cases involve judgment calls, not checklists. Our Attorney Review Board brings multiple experienced attorneys into the strategy process before critical submissions are made, similar to how complex medical cases are reviewed by a tumor board. This structure reduces blind spots and prevents avoidable damage to the record.

Record Control Strategy
The most important part of a clearance case is not the final decision, but what gets written into the permanent record. Our Record Control Strategy focuses on how issues are framed, whether concerns are fully resolved or left open, and how today’s language may be reused in future reinvestigations, polygraphs, promotions, or upgrades.
→ Why record control is critical in security clearance cases

Niche security clearance lawyers, not general practitioners
Security clearance law is its own discipline. Our clearance attorneys focus on clearance matters, our federal employment lawyers focus on employment cases, and our military lawyers focus on military law. This specialization is decisive. Lawyers who primarily handle unrelated areas of law often miss clearance-specific risks and downstream consequences.
→ Why niche clearance lawyers outperform general practitioners
