A felony conviction can seriously affect a security-clearance decision, but there is no single rule that every felony permanently bars every form of clearance. The access sought, applicable statutory restrictions, and whole-person adjudication all matter. Federal job eligibility is also different from clearance eligibility.
Review the conduct and mitigation
The national adjudicative guidelines address criminal conduct and related concerns such as honesty, judgment, substance use, and financial behavior. Relevant mitigation can include time elapsed, rehabilitation, compliance with sentence requirements, changed circumstances, and reliable evidence that the conduct is unlikely to recur. No one factor guarantees approval. [1]
Answer the actual questionnaire
SF-86 questions have particular timeframes and exceptions, including questions that reach beyond a general recent-history period. Do not assume an expungement, dismissed charge, or completed probation may be omitted. Read the exact question and instructions and explain the disposition accurately. [2]
For example, a decades-old conviction with documented rehabilitation presents a different record from recent repeated conduct and incomplete disclosure. Concealing the older case can create a new candor issue.
Prepare records before review
Obtain the charging document, disposition, sentence-completion evidence, treatment or rehabilitation records where relevant, and a consistent chronology. Check whether a particular type of sensitive access has a special statutory bar or waiver procedure.
If the agency issues adverse findings, use the stated response or appeal process and deadlines. An ordinary hiring appeal may not be the clearance-review procedure.
The prison-sentence restriction has a precise scope
Section 3343(c) generally disqualifies a covered person from clearances providing access to special access programs, Restricted Data, or sensitive compartmented information when the person was convicted, sentenced to more than one year, and actually incarcerated for at least one year, absent an express written waiver under the statute. The sentence and actual incarceration conditions both matter. A meritorious case may qualify for the specified waiver process; it is not a general entitlement. [3]
This statutory inquiry is distinct from the guidelines’ broader evaluation of criminal conduct, which can include credible conduct without a conviction. Someone outside the precise statutory condition can still have a serious guideline concern, while someone seeking a waiver needs more than a favorable informal recommendation. [1]
