How to Get a Security Clearance: Sponsorship, SF-86, and Investigation

To get a security clearance, you need a federal agency or a cleared defense contractor to sponsor you for a specific job that requires access to classified information; they initiate the process, the Defense Counterintelligence and Security Agency (DCSA) investigates your background, and a separate adjudicator decides whether granting you access is consistent with national security. You cannot apply on your own, the investigation costs you nothing, and the wait is usually measured in months rather than weeks.

Get Sponsored First

Sponsorship is the entire starting point. A cleared contractor or federal agency has to determine that a position genuinely requires classified access, then formally request an investigation on your behalf.¹ No job offer that needs a clearance, no clearance. The sponsoring organization’s Facility Security Officer or security office kicks off the process once they confirm the position qualifies, and that sponsorship lasts only as long as your employment does. Leave the job or lose the need, and the basis for the clearance goes with it.

You also have to be a United States citizen. Executive Order 12968 limits classified access to U.S. citizens who have completed an appropriate background investigation. Narrow exceptions exist for immigrant aliens or foreign nationals with special expertise, but only for specific programs and only up to the classification level the U.S. government has approved for release to that person’s country of citizenship.² These exceptions are uncommon.

Dual citizenship alone will not sink you. Under the adjudicative guidelines, holding another country’s citizenship, without any objective conflict or concealment, is not a bar. What creates problems is actively exercising foreign citizenship rights, such as using a foreign passport instead of your U.S. one or taking a government post in another country. If your dual status comes from parentage or place of birth and you have not acted on it, adjudicators generally view that favorably, and willingness to renounce can help too.³

Know Which Level the Job Requires

Executive Order 13526 defines three levels of classification by the damage unauthorized disclosure could cause to national security: Confidential (damage), Secret (serious damage), and Top Secret (exceptionally grave damage).⁴

The level of the position sets the depth of the investigation. A Secret investigation typically looks back five years and focuses on criminal records, credit reports, and local law enforcement checks. A Top Secret investigation goes back ten years and adds in-person interviews with people who know you.⁵

Some jobs, especially at intelligence agencies like the CIA, NSA, and DIA, require access beyond Top Secret. Sensitive Compartmented Information (SCI) access adds extra vetting, including a counterintelligence-scope polygraph.⁶ Special Access Programs (SAPs) impose their own additional requirements. Both use Top Secret as a baseline and layer more screening on top.

Complete the SF-86

The Standard Form 86, formally called the Questionnaire for National Security Positions, is where the process becomes real work. It asks you to account for the last ten years of your life in detail, with some “have you ever” questions carrying no time limit at all.⁷ You submit it electronically through DCSA’s eApp system, which replaced the older e-QIP platform.⁸

Before you start, pull together:

Every address where you have lived for the past ten years, with no gaps and a verifier for each residence.⁵
Ten years of employers, addresses, supervisor contact information, and dates, again with no gaps. Unemployment and self-employment count.
Foreign nationals you have had close contact with over the past seven years, plus dates and destinations for foreign travel.
Any bankruptcies filed in the past seven years, debts currently more than 120 days past due, and other financial issues the form specifically asks about.
Past drug use, criminal history, mental health treatment, and every school you attended over the past decade.

Physical addresses only. P.O. boxes are not accepted. Most people badly underestimate how long the form takes, and starting a personal records file before you actually need a clearance is one of the most practical things you can do.

Accuracy matters more than perfection. Nobody remembers every detail from a decade ago, and honest gaps in memory will not destroy your application. Lying will. Knowingly making a false statement on the SF-86 is a federal crime under 18 U.S.C. § 1001, punishable by up to five years in prison.⁹ Adjudicators care more about concealment than about the underlying issue. Something disclosed and explained is manageable; something hidden and later discovered often is not.

What Happens During the Investigation

Once your SF-86 is in, DCSA runs the investigation. Investigators verify what you reported through criminal databases, credit reports, and public records. For Top Secret cases, they also interview former employers, coworkers, neighbors, and other references in person.¹⁰ They are not searching for a perfect life. They are looking for patterns that suggest you could be coerced, compromised, or that your judgment is not reliable enough to protect classified information.

Processing times fluctuate. As of early 2026, the average Top Secret investigation exceeds 240 days and Secret investigations average more than 130 days. These are averages; extensive foreign travel, residence in multiple states, or issues that require follow-up all add time.

Because investigations run long, your sponsor may request an interim clearance so you can start work sooner. DCSA’s Adjudication and Vetting Services reviews your SF-86, fingerprint results, proof of citizenship, and any available local records, then makes a preliminary call.¹¹ An interim stays in place until the full investigation concludes. Not everyone gets one; if the preliminary records raise a flag, the interim is denied and you wait for the full result.

How the Decision Gets Made

The investigation produces a file. A separate adjudicator, not the investigator, decides whether granting access is consistent with national security. The adjudicator applies the 13 guidelines in Security Executive Agent Directive 4 (SEAD 4), which governs all national security eligibility determinations.³ The guidelines cover allegiance to the United States, foreign influence, foreign preference, sexual behavior, personal conduct, financial considerations, alcohol consumption, drug involvement, psychological conditions, criminal conduct, security violations, outside activities, and misuse of information technology.

Each guideline lists conditions that raise concern and conditions that mitigate it. The adjudicator uses a “whole person” approach, weighing the totality of your life rather than any isolated fact. Any remaining doubt gets resolved in favor of national security, not the applicant.

Outright denials are uncommon, running roughly 2 to 5 percent of applications. When they happen, three areas dominate the list. Financial problems come up most often; the concern is not past hardship but unresolved debt or reckless spending that could make you vulnerable to bribery or coercion. There is no specific debt-to-income ratio that disqualifies you, and the strongest mitigation is concrete evidence of payment plans, counseling, or documented changes in habits. Drug involvement is consistently near the top too. Old experimental use with a long clean stretch is potentially mitigable; recent or ongoing use, or any use while holding a clearance, is much harder to overcome. Personal conduct problems, especially dishonesty during the investigation, are treated as an independent disqualifying issue separate from whatever you were trying to hide. More applications fail here than people expect.

If You Are Denied

A denial is not automatically the end. If the adjudicator finds disqualifying information, you receive a Statement of Reasons (SOR) laying out the specific concerns, and you have the right to respond in writing with evidence and explanations.

For Department of Defense clearances, the appeal runs through the Defense Office of Hearings and Appeals (DOHA). You can request a personal appearance before an administrative judge to testify, present witnesses, and submit documents. You may represent yourself, bring a friend or colleague to help, or hire an attorney at your own expense. The judge conducts the hearing so that someone without legal training can follow it, and you are not placed under oath, though lying remains a federal crime under 18 U.S.C. § 1001.¹²

If the judge rules against you, you can file a notice of appeal with the DOHA Appeal Board within 15 calendar days of the decision. Your written appeal brief is due within 45 days of that decision. The Board’s review is limited to whether the judge made an error, not whether it would have decided the same evidence differently, and it cannot consider new evidence outside the original record. There is generally no further appeal beyond the Board.¹³ Deadlines are strict: documents must be received by the due date, not postmarked. If the deadline falls on a weekend or federal holiday, it rolls to the next business day.

Keeping the Clearance Once You Have It

Getting cleared is half the job. Keeping it requires ongoing compliance.

The old cycle of reinvestigating clearance holders every five or ten years is being phased out under Trusted Workforce 2.0. In its place, DCSA now runs continuous vetting, which pulls automated data from criminal, terrorism, financial, and public records databases at any point during your eligibility.¹⁴ A speeding ticket generates little interest. A new felony charge or a sudden unexplained wealth spike does.

You also have to self-report certain life events to your security office. Security Executive Agent Directive 3 (SEAD 3) spells out what must be reported, with obligations that scale up by clearance level.¹⁵ Everyone with a clearance reports unofficial foreign travel (including deviations from approved itineraries within five business days of return), contact with known or suspected foreign intelligence entities, and certain ongoing associations with foreign nationals. Secret and Confidential holders also report things like applying for foreign citizenship, obtaining a foreign passport, or becoming more than 120 days delinquent on any debt. Top Secret holders add foreign bank accounts, foreign property ownership, direct involvement in foreign business, marriage to or cohabitation with a foreign national, bankruptcy, garnishment, and unusual asset influxes of $10,000 or more, including inheritance and gambling winnings. Failing to report what you owe is itself a security concern under the personal conduct guideline.

If you already hold a valid clearance and move to another federal agency or contractor, you generally do not need a brand-new investigation. Security Executive Agent Directive 7 requires agencies to accept existing investigations and eligibility determinations at the same or higher level, provided the investigation is no more than seven years old and no new disqualifying information has emerged. The new agency cannot force a fresh SF-86 or re-adjudicate your prior investigation simply because you changed employers, though it may ask you to identify changes since your last submission. Reciprocity does not apply if the clearance was granted on an interim or temporary basis, or if it is currently suspended or revoked.¹⁶
