Federal law does not establish the broad checklist of automatic disqualifiers commonly found online. What it establishes is narrower: 50 U.S.C. § 3343 sets out one non-waivable statutory prohibition and three waivable statutory disqualifications, and the three waivable ones apply only to specified categories of access.
Two qualifications belong up front. That statute is not the complete universe of restrictions, and other authorities can impose limits it does not list. And none of these provisions is self-executing. Each still requires a factual determination reached through administrative review.
With that framing in place, here is what the statute actually contains.
Federal law prohibits an agency head from granting or renewing a security clearance for a covered person who is an unlawful user of a controlled substance or an addict.
No waiver provision attaches to this prohibition, which distinguishes it from the three discussed below. It reaches every clearance level rather than a subset. And "covered person" includes officers and employees of federal contractors, not only federal employees and military members.
What "no waiver" does not mean. The absence of a waiver does not make the prohibition automatic in the sense people usually intend. Whether a person is an unlawful user of a controlled substance or an addict is a factual question, and it gets answered through investigation and adjudication like any other question in the process. There is no database lookup that produces this result. What the absence of a waiver means is that once that determination is made, no agency head has authority to grant the clearance anyway.
Current status versus history. The provision is written in the present tense and addresses current unlawful use and current addiction. Prior use that has ended is ordinarily evaluated under Guideline H of the adjudicative guidelines, which covers drug involvement and substance misuse, rather than under this statutory prohibition. That routing is the general pattern and not a guarantee about any particular case.
Three further disqualifications sit in a separate subsection of the same statute. Two things are true of all three.
They reach only clearances providing access to special access programs, Restricted Data, or sensitive compartmented information. They do not apply to a standard Confidential, Secret, or Top Secret clearance without one of those access categories layered on.
And an agency head may issue an express written waiver in a meritorious case where mitigating factors exist.
Certain criminal convictions: the person was convicted in a United States court of a crime, was sentenced to imprisonment for a term exceeding one year, and was incarcerated as a result of that sentence for not less than one year. All three conditions have to be present. A felony conviction alone does not reach this provision, and neither does a sentence exceeding a year that resulted in less than a year of actual incarceration.
Dishonorable discharge or dismissal: the person was discharged or dismissed from the Armed Forces under dishonorable conditions. Other-than-honorable and general discharges are different characterizations and are not what this provision names.
A mental incompetence determination: the person is mentally incompetent as determined by an adjudicating authority, based on an evaluation by a qualified mental health professional employed by or approved by the government.
That last one is routinely misread as treatment being disqualifying. It is not. The statute directs that no negative inference may be raised solely because someone sought mental health counseling. A formal incompetence determination by an adjudicating authority is a specific legal finding, not a diagnosis and not a course of care.
A waiver is not an approval. Waiving a statutory disqualification removes the statutory bar. It does not resolve the underlying conduct. That conduct still goes through adjudication under the guidelines, and it can still result in denial there. A waiver moves the case from "prohibited by statute" to "adjudicated on the merits," which is a meaningful change and not the same as a favorable outcome.
Do not plan around getting one. Waivers are available in meritorious cases. They are not routinely granted, and there is no public accounting of how often they are used. Agency heads report waivers to Congress, but that reporting does not produce a published frequency anyone can point to. Treat the waiver as an authority that exists rather than as a pathway you can count on.
Section 3343 is one authority among several. Agency-specific policy, intelligence community directives governing sensitive compartmented information, department-level requirements at agencies running their own clearance programs, and requirements attached to particular positions or programs can all impose conditions the statute does not address.
The practical consequence is that "not barred by statute" and "eligible" are different statements. Confirm the specific requirements for the specific access with the facility security officer at the sponsoring employer.
Search results on this topic hand you a list: debt, bankruptcy, foreign relatives, arrests, gambling, alcohol, social media activity. None of those appears in the statute as a bar.
They come from the adjudicative guidelines, and the guidelines are not structured as a list of disqualifiers. Each one pairs conditions that raise a security concern with conditions that can mitigate that concern. An adjudicator weighs both against the whole person: the recency of the conduct, how often it happened, the circumstances around it, the person's age at the time, evidence of rehabilitation, and the likelihood of recurrence.
A concern begins the analysis rather than ending it. This is why two applicants with similar histories can receive different determinations, and why no quiz can tell you whether you will be cleared.
The requirements page covers what each guideline examines
These are not statutory bars. They are threshold conditions, and they stop things just as effectively.
No sponsor: you cannot initiate a clearance for yourself. A federal agency or a cleared employer with a position requiring classified access has to start the process.
Citizenship: eligibility for access to classified information requires United States citizenship.
Refusal to complete the process: declining to provide required information, refusing to sign the necessary releases, or abandoning the investigation ends the case.
It adds a concern rather than replacing one.
Deliberate omission or falsification on the security form raises concerns under Guideline E, which covers personal conduct. Those concerns sit alongside whatever was concealed, not in place of it. An applicant who omits a resolved debt now has both a financial question and a candor question, and the candor question was avoidable.
Whether the concealment or the underlying conduct weighs more heavily depends on what the conduct was. Some conduct is serious enough that disclosure would not have saved the case. Some is minor enough that the omission becomes the more significant problem. The general point holds without needing to rank them: disclosure removes one of the two concerns, and concealment guarantees both.
Disclose it completely, in the first instance. Bring documentation showing what happened and what has changed since. State it rather than characterizing it.
Then let the mitigating conditions do their work. Time, rehabilitation, changed circumstances, and infrequency all carry weight under the guidelines. They carry less weight when the adjudicator learns the facts from an investigator instead of from you.
One caution. If your situation touches one of the statutory provisions above, particularly the conviction thresholds or a formal incompetence determination, that is a question for a security clearance attorney and for the facility security officer at the sponsoring employer. It is not a question for an article.

Frequently Asked Questions
Is a felony an automatic disqualifier for a security clearance? No. The statutory provision requires a conviction in a United States court, a sentence exceeding one year, and actual incarceration of not less than one year. All three have to be present, a waiver is available in a meritorious case, and the provision reaches only access to special access programs, Restricted Data, or sensitive compartmented information. A felony conviction is still evaluated under the adjudicative guidelines regardless.
Does past drug use automatically disqualify you? No. The statutory prohibition addresses a person who is currently an unlawful user of a controlled substance or an addict. Prior use that has ended is ordinarily evaluated under Guideline H, where mitigating conditions are available.
Can a dishonorable discharge be waived? An agency head may issue an express written waiver in a meritorious case with mitigating factors. Waivers are not routinely granted. The provision also reaches only special access programs, Restricted Data, and sensitive compartmented information, and other-than-honorable and general discharges are not what it names.
Does seeking mental health treatment disqualify you? No. Federal law directs that no negative inference may be raised solely on the basis of seeking mental health counseling. The statutory provision concerns a formal mental incompetence determination made by an adjudicating authority.
Is 50 U.S.C. § 3343 the complete list of things that can bar a clearance? No. It is one authority. Agency policy, intelligence community directives, department-level requirements, and conditions attached to specific positions or programs can impose restrictions the statute does not address.
