The SF-86 is 127 pages — and every answer is verified.

If you are preparing to complete your first SF-86, facing a reinvestigation, or navigating a concern about specific disclosures, this guide covers the complete framework. The SF-86 is detailed, demanding, and legally consequential — but understanding what investigators examine and how to approach sensitive sections makes the process manageable.

Section I The SF-86 in the clearance process

The SF-86 is the starting point of every national security clearance investigation at Tier 3 (Secret) and Tier 5 (Top Secret / SCI). Understanding its role in the overall process helps you complete it effectively.

Purpose of the form

Under E.O. 12968 Section 3.1 and 5 CFR Part 732, the SF-86 establishes the factual baseline for the background investigation. Investigators use SF-86 answers to:

• Identify the scope of investigation (what must be verified)
• Generate records checks (FBI, state criminal, credit bureau, agency databases)
• Identify interview subjects (employers, neighbors, references, spouses)
• Target foreign contact and travel review (counterintelligence implications)
• Surface issues requiring further investigation under SEAD 4 guidelines

Every answer on the SF-86 generates investigative activity. Incomplete answers generate follow-up requests; incorrect answers generate extended investigation; false answers generate adverse adjudicative outcomes.

NBIS eApp platform

As of late 2024, all federal agencies use the NBIS eApp platform to initiate background investigations, replacing the legacy e-QIP system. Key features of eApp:

• Modern web-based interface with automated validation
• Pre-populated fields from prior filings when available
• Session saving (progress is preserved between sessions)
• Session timeout protection (typically 15-30 minutes inactive)
• Accessibility compliance with 508 standards
• Integration with the Individual Experience Portal (IEP) for case status tracking

The typical flow: your agency's security office sponsors you in NBIS eApp, you receive an invitation email with login credentials, you complete the SF-86 sections, and you submit to the sponsor for review and release to DCSA.

What happens after submission

After you submit the SF-86:

1. Sponsor review — your security office reviews completeness before releasing to DCSA
2. Case initiation — DCSA opens the investigation and begins automated records checks
3. Records verification — FBI name check, OPM records, credit checks, law enforcement checks
4. Field investigation (Tier 5) — investigator assigned; subject interview scheduled; neighbors, employers, references contacted
5. Report generation — Report of Investigation (ROI) compiled with all findings
6. Adjudication — agency or DCSA Consolidated Adjudications Services reviews against SEAD 4 guidelines
7. Decision — favorable determination (clearance granted), statement of reasons (SOR) if concerns, or denial

Under current DCSA metrics, 90% of Tier 3 investigations complete within approximately 90 days and 90% of Tier 5 investigations complete within approximately 180 days, though timelines vary by case complexity.

Legal significance of signature

When you sign the SF-86 certification, you acknowledge:

• The information provided is true and complete to the best of your knowledge
• Falsification is punishable under 18 U.S.C. 1001 by up to 5 years imprisonment and fines
• You consent to information being released by third parties for the investigation
• Information may be shared with other federal agencies under Privacy Act routine uses
• Failure to provide required information may adversely affect your clearance eligibility
• You have continuing obligations to report changes under SEAD 3 after approval

The signature is legally binding. Investigators treat intentional false statements as both a security concern (personal conduct under Guideline E) and a potential criminal matter.

Section II Before you start — preparation materials

The worst approach to the SF-86 is opening eApp cold and attempting to reconstruct your history from memory. The right approach is gathering documentation before you begin.

Residence history — 10 years

Every address you have lived at for the past 10 years, including:

• Exact street address with apartment/unit number
• City, state, zip code (and country if outside the US)
• Precise move-in and move-out dates (month and year minimum; exact date preferred)
• Whether you rented or owned
• A verifier for each address — someone who can confirm you lived there (landlord, neighbor, family member). Each verifier should have name, address, phone, and email.

Common sources for residence reconstruction: tax returns, utility bills, bank statements, lease agreements, driver's license history, voter registration records.

Employment history — 10 years

Every employer, including part-time and contract work, with:

• Employer name and complete address
• Position title
• Supervisor name, title, and contact (phone, email)
• Exact start and end dates
• Reason for leaving
• Gaps between jobs must be explained (unemployment, school, travel, caretaking)

Sources: W-2s, tax returns, LinkedIn profile, prior SF-86 filings, HR records from previous employers.

Education — 10 years

• All schools attended (college, graduate, professional, vocational)
• Dates of attendance (start and end, with exact dates)
• Degrees awarded and dates conferred
• Contact information for each school (registrar's office)

Foreign contacts and travel

Under the SF-86's reporting standard, foreign contacts means individuals who are foreign nationals (not US citizens) with whom you have close and continuing contact — relationships characterized by frequent communication, close personal or professional bonds, or financial relationships. Information needed:

• Name, date of birth, country of citizenship
• Relationship type (family, friend, colleague, business)
• Nature and duration of contact
• Method of communication (frequency, platform)
• Whether the contact has any association with foreign government, military, or intelligence

Foreign travel (for all purposes — personal, business, government) within the past 7 years (some sections 10 years), including dates and countries. US military deployments are typically listed separately in military history.

Financial records

Pull your credit report from all three bureaus (Equifax, Experian, TransUnion) before starting. Know what's on it. Common financial disclosure items:

• Delinquencies over 120 days
• Collections accounts
• Bankruptcies (all, with dates and case numbers)
• Tax liens, federal or state
• Judgments
• Repossessions
• Foreclosures
• Defaulted loans (including student loans)

For each financial item, know: creditor, original amount, current status, payment plan if any, and any supporting documentation.

References

You will need verifiable references — people who know you well enough to speak to your character, reliability, and trustworthiness. Investigators will contact them directly. Give references a heads-up that they may be contacted — a cold call from an investigator is not helpful to your case.

Criminal and legal records

• All arrests, charges, and convictions (even if expunged or sealed — the SF-86 requires reporting of many even if sealed)
• Case numbers, dates, charges, disposition
• Military court-martial records if applicable
• Civil court actions (lawsuits, divorce decrees, restraining orders)

Prior SF-86 filings

If you have completed a prior SF-86, retrieve a copy if possible (your agency security office may have one on file). Compare your current answers against prior filings — discrepancies are a flag investigators will ask about.

Section III Section-by-section walkthrough

The SF-86 has approximately 29 numbered sections (the number varies slightly by version). Each section has a specific focus and connects to one or more SEAD 4 adjudicative guidelines.

Sections 1-8 — Personal identifying information

Sections 1 through 8 cover core identity:

• Section 1 — Full legal name, including all aliases, maiden names, and name changes
• Section 2 — Date and place of birth
• Section 3 — Other names used (including maiden, former married, legal changes)
• Section 4 — Social Security Number
• Section 5 — Other names used
• Section 6 — Your identifying information (height, weight, hair, eyes — being phased out under PVQ)
• Section 7 — Contact information (phone, email, address)
• Section 8 — US Passport information

Investigators use these sections for identity verification — matching you against federal records, credit bureau data, and criminal databases. Common errors: mismatched SSNs (investigators cross-check with the Social Security Administration), incorrect DOBs, omitted aliases or maiden names.

Sections 9-10 — Citizenship

Section 9 covers your citizenship status, including:

• Current citizenship (US by birth, US naturalized, dual citizenship, foreign)
• Date and place of naturalization if applicable
• Date and place of birth abroad if applicable
• Any foreign citizenship held
• Documentation of US citizenship (passport, birth certificate, naturalization certificate)

Section 10 covers dual citizenship specifically. Dual citizenship is not automatically disqualifying but is examined under SEAD 4 Guideline C (Foreign Preference) — whether the individual has acted or would act to benefit a foreign country over the United States. Many clearance holders have dual citizenship.

Section 11 — Where You Have Lived (10 years)

Complete residence history with addresses, dates, and verifiers. Every address counts — even temporary stays at family members' homes during transitions. Gaps between addresses are flagged. Investigators conduct neighborhood checks at a sample of listed addresses.

Section 12 — Your Education

Schools attended, dates, and degrees. Verify against official transcripts. Investigators verify education through registrar contacts.

Section 13 — Your Employment Activities (10 years)

Complete employment history. Includes military service, civilian federal employment, private sector, self-employment, part-time, contract, and periods of unemployment. Every gap must be explained. Investigators verify through employer contacts — large gaps trigger additional investigation.

Section 14 — Selective Service Record

For male applicants, Selective Service registration status. Under the PVQ this question is being removed because the information is available through other means.

Section 15 — Military History

All military service including:

• Branch, rank, service dates
• Type of discharge (honorable, general, other than honorable, dishonorable)
• Foreign military service
• Reserve and National Guard service

Dishonorable discharge is a Bond Amendment disqualifier. Other discharge types are evaluated under SEAD 4 Guideline J (Criminal Conduct) and Guideline E (Personal Conduct).

Section 16 — People Who Know You Well

Typically three references who have known you well for the past 7 years. Choose references who can speak to your character, reliability, and trustworthiness. Investigators will contact them directly.

Section 17 — Marital/Relationship Status

Current and former spouses, including dates of marriage and divorce. Also covers cohabitants. For each spouse/partner, identifying information and, if a foreign national, citizenship and related details.

Section 18 — Relatives

Parents, step-parents, siblings, children, and other relatives. Includes foreign national relatives with citizenship, country of residence, and contact information. This section is critical for SEAD 4 Guideline B (Foreign Influence) analysis. Investigators analyze foreign relatives for influence risk.

Section 19 — Foreign Contacts

Foreign nationals with whom you have close and continuing contact. The reporting standard is "close and continuing" — casual acquaintances do not meet the threshold. What counts:

• Foreign national spouses or domestic partners
• Foreign national close friends you communicate with regularly
• Foreign national business associates or ongoing professional contacts
• Foreign national family members you maintain contact with
• Any foreign national whom you have shared sensitive or personal information

Foreign contacts are examined under Guideline B (Foreign Influence). The specific country matters — contacts in countries designated as of heightened concern receive more scrutiny.

Section 20 — Foreign Activities

Covers foreign travel, foreign business interests, foreign financial accounts, and foreign passports. Specific items:

• Section 20A — Foreign financial interests (foreign accounts, investments, property ownership)
• Section 20B — Foreign business, professional activities, and government contacts
• Section 20C — Foreign countries visited (past 7 years)

Each foreign trip requires dates, countries, purpose, and who you visited or what you did. Frequent travel to countries of heightened concern generates expanded investigation.

Section 21 — Psychological and Emotional Health

This is the mental health section. The form explicitly states that mental health treatment in and of itself is not a reason to deny or revoke eligibility. Reportable items:

• Declaration of mental incompetence by a court or administrative agency (Bond Amendment disqualifier)
• Court-ordered consultation or treatment
• Hospitalization for mental health reasons
• Specific diagnosed conditions that could affect judgment, reliability, or trustworthiness (psychotic disorders, severe mood disorders, substance use disorders)

NOT reportable: routine counseling, marriage counseling, grief counseling, stress adjustment counseling, routine therapy for anxiety or depression without hospitalization. The form explicitly excludes these.

Section 22 — Police Record

Arrests, charges, and convictions. Covers:

• Any arrest — even without charges
• Any charge — even if dismissed or nolle prossed
• Any conviction — including misdemeanors
• Domestic violence-related charges or convictions
• Alcohol or drug-related arrests
• Traffic offenses with substantial fines or jail time
• Some arrests must be reported even if expunged or sealed

The instructions explicitly require reporting of many items that a non-federal background check might not include. Read each subsection carefully. Omission of an arrest that later surfaces in investigation is a major Guideline E concern.

Section 23 — Illegal Use of Drugs or Drug Activity

Use of controlled substances as defined by federal law (including marijuana, which remains a federal Schedule I substance despite state legalization). Reportable:

• Any illegal drug use in the past 7 years
• Drug use while holding a security clearance or federal position (any time, not just 7 years)
• Drug use while employed as a law enforcement officer, prosecutor, or courtroom official (any time)
• Drug manufacture, trafficking, or distribution (any time)
• Prescription drug misuse

Current drug use (within the past year for most agencies) is typically disqualifying. Past drug use is evaluated under Guideline H (Drug Involvement) — factors include recency, frequency, nature, age at use, and commitment to abstinence.

Section 24 — Use of Alcohol

Covers alcohol-related incidents:

• Alcohol-related arrests (DUI, public intoxication, disorderly conduct)
• Alcohol counseling or treatment
• Alcohol use that impacted work, family, or judgment
• Diagnosed alcohol use disorder

Evaluated under Guideline G (Alcohol Consumption).

Section 25 — Investigations and Clearance Record

Prior security clearance investigations and determinations. Includes agency, date, type, and outcome. Also covers denials or revocations of clearances, access suspensions, and similar adverse security actions.

Section 26 — Financial Record

Financial disclosure covering:

• Bankruptcies (all, lifetime in some subsections; 7 years in others)
• Tax liens (federal and state)
• Delinquencies over 120 days
• Collections accounts
• Judgments, repossessions, foreclosures
• Failure to file tax returns
• Gambling problems

Evaluated under Guideline F (Financial Considerations). For detailed coverage, see Workplace Topic 37 on Financial Issues.

Section 27 — Use of Information Technology Systems

Covers IT misconduct:

• Unauthorized access to government or business systems
• Unauthorized modification or destruction of data
• Unauthorized entry into classified information systems
• Use of IT systems for unauthorized purposes

Evaluated under Guideline M (Use of Information Technology Systems).

Section 28 — Involvement in Non-Criminal Court Actions

Civil court involvement including lawsuits, divorce proceedings, restraining orders, and other civil actions. Generally examined for patterns suggesting judgment issues or untrustworthiness.

Section 29 — Association Record

Membership in or association with organizations that advocate overthrow of the US government, dedicate to use of violence or other unlawful means, or seek to deprive individuals of their rights. This section is narrowly tailored to specific categories of concerning organizations — standard political, religious, or civic organizations are not reportable here.

Signature and certification

The final section requires signed certification that the information is true and complete. Signing without having completed all sections accurately exposes you to 18 U.S.C. 1001 liability even if your intent was not to deceive. Review the entire form before signing.

Section IV Common red flags investigators hunt for

Beyond the specific items disclosed in each section, investigators examine patterns and characteristics of the SF-86 itself. Common red flags:

Inconsistencies across sections

The SF-86 asks similar information in different sections. Investigators flag:

• Employment dates that don't match residence dates (working in one city while listing residence in another)
• Foreign travel listed in Section 20 that doesn't match employment in Section 13
• Education dates that conflict with employment dates
• Foreign relatives listed in Section 18 not mentioned in Section 19 foreign contacts
• Prior clearance investigations in Section 25 not consistent with employment history

Gaps in time

Unexplained gaps in residence, employment, or education history flag investigators. Common gaps that need explanation:

• Unemployment periods longer than 30 days
• Residence gaps between move-out and move-in dates
• Education completed but no employment or accompanying activity for an extended period
• Periods of long foreign residence without clear purpose

Every gap should be explained in the Optional Comments or Remarks section. "Unemployed" is an acceptable status; "unknown" is not.

Discrepancies with prior SF-86s

Prior SF-86 filings are retained and compared to current filings. Discrepancies generate follow-up:

• Employment dates that differ between filings
• Residences listed in prior filing but omitted in current
• Foreign contacts in prior filing now omitted
• Drug use disclosed in prior filing now denied
• Different arrest dispositions across filings

Any discrepancy requires explanation. "I listed it incorrectly before" is an acceptable explanation if documented truthfully. "I didn't remember last time" requires explanation of what changed.

Vague or incomplete answers

Specific answers advance investigation; vague answers delay it. Examples of problematic phrasing:

• "Approximately 2018" (should be exact month and year)
• "Somewhere in the Dallas area" (should be exact address)
• "I think the supervisor was John" (should be full name and verified contact)
• "Several" or "a few" (should be exact number)
• "Minor incident" (should describe the incident with facts)

Sophisticated language suggesting concealment

Experienced investigators look for linguistic patterns that suggest careful wording to avoid disclosure:

• Technical denial — "I have never been convicted" may be technically true while omitting arrests or charges
• Temporal qualifiers — "In the past 5 years" when the question asks about past 7 years
• Narrow interpretation — answering "No" to "Have you used illegal drugs?" based on personal belief that marijuana is legal in your state
• Minimization — "Just one minor incident" when the item is significant

The adjudicative process considers not just the disclosed facts but the candor and completeness of disclosure. Literal truthfulness that obscures material information raises Guideline E concerns.

Refusal to disclose or hesitation

Investigators note applicant reluctance during subject interviews. Repeated "I don't remember" responses to questions about the past 10 years, defensive reactions to specific topics, or refusal to discuss matters specifically raised on the SF-86 are flags.

Information discovered elsewhere

The largest category of red flags is information the investigator discovers that was not disclosed on the SF-86:

• Credit report shows delinquencies not disclosed in Section 26
• FBI records show arrests not disclosed in Section 22
• Previous agency files show prior clearance issues not disclosed in Section 25
• Employment verification shows different dates or title than claimed
• Social media or public records show foreign contacts not disclosed in Section 19
• Neighbor interviews describe a spouse or relative not disclosed in Section 17 or 18

Discrepancies between SF-86 disclosures and investigator findings are the most common cause of extended investigation and clearance adverse action.

Section V Handling sensitive sections — drugs, finances, mental health

Three sections generate the most applicant anxiety: drug use (Section 23), financial issues (Section 26), and mental health (Section 21). Strategies for each:

Drug use (Section 23)

The SF-86 asks about illegal drug use — including marijuana, which remains a federal Schedule I controlled substance regardless of state legalization. Key principles:

• Current drug use is typically disqualifying — most agencies treat any illegal drug use within the past year as an absolute bar. The 2025 PVQ proposes a 90-day window for marijuana specifically, but federal law has not changed.
• Past use is evaluable — under Guideline H, past drug use is evaluated based on recency, frequency, nature, age at use, and commitment to abstinence
• Disclosure is required — use within the reporting scope must be disclosed regardless of state law
• Honesty is essential — drug use patterns often surface through medical records, interview statements, and other sources. Concealment is the worse option.

For drug-related disclosures, provide: the drug(s) used, dates or approximate frequency, circumstances (social, experimental, addictive), age at time, steps taken to stop (if applicable), and current commitment to abstinence. A signed statement committing to abstinence is often treated favorably.

Financial issues (Section 26)

Financial disclosures are among the most common clearance concerns because almost everyone has some financial history. Key principles:

• Disclose everything in scope — delinquencies, collections, bankruptcies, tax issues, judgments
• Don't minimize — "I had some bills" is weaker than "I had a credit card delinquency of $8,500 that went to collections in 2022 and was resolved through a payment plan in 2024"
• Show resolution — active resolution (payment plan, debt management program, tax installment agreement) mitigates concerns
• Context matters — circumstances beyond the person's control (job loss, medical emergency, divorce) are mitigating
• Don't let debt go unaddressed — ignored debt is more concerning than actively managed debt

For complete coverage of financial issues in clearance context, see Workplace Topic 37 on Clearance Financial Issues.

Mental health (Section 21)

The mental health section is written carefully to encourage treatment-seeking without creating disincentive. Key principles:

• Treatment is not a disqualifier — the form explicitly states this
• Most treatment is not reportable — routine counseling, therapy for life stressors, marriage counseling, grief counseling are specifically excluded
• What's reportable is limited — court-ordered treatment, hospitalization, mental incompetence declaration, specific judgment-affecting conditions
• Security officers cannot pressure treatment disclosure — providers generally cannot be forced to disclose treatment details without consent
• Don't avoid needed care — untreated mental health issues are a greater concern than treated ones

Under Guideline I, favorable prognosis from a treating mental health professional is a powerful mitigating factor. Obtain a letter if relevant.

Foreign contacts (Section 19)

Foreign contacts generate substantial anxiety but are rarely disqualifying. Key principles:

• The reporting standard is "close and continuing" — casual acquaintances don't qualify
• Family relationships are common — foreign-born spouses, parents, siblings are routine and clearance holders with foreign family are common
• Country matters — contacts in countries of heightened concern (SEAD 3 Annex A) receive more scrutiny
• Nature of contact matters — regular communication, close personal bonds, financial relationships are more concerning than occasional contact
• Government/military/intelligence connections matter — foreign contacts associated with foreign government, military, or intelligence receive the highest scrutiny

Full disclosure is the correct approach. Failure to disclose a foreign contact that surfaces through investigation is a substantial Guideline E and Guideline B concern.

Section VI How investigators verify your answers

Understanding the verification methods helps applicants prepare. Investigators use different methods depending on investigation tier.

Tier 3 (Secret) verification

Tier 3 investigations rely primarily on automated records checks and limited field work:

• FBI Name Check — searches FBI indices for arrest records, investigations, and other findings
• OPM records check — prior federal investigations and employment records
• Credit bureau check — all three major bureaus (Equifax, Experian, TransUnion)
• Local law enforcement check — requests to local agencies at listed residences
• Employment verification — written inquiries or phone calls to listed employers
• Education verification — contact with registrar's offices
• Reference check — often by written inquiry rather than in-person interview

Tier 5 (Top Secret / SCI) verification

Tier 5 adds extensive field investigation:

• Subject interview — in-person interview with applicant covering all SF-86 sections and any follow-up issues
• Neighbor interviews — in-person interviews with neighbors at recent residences
• Coworker interviews — interviews with supervisors, coworkers, and subordinates at recent employers
• Reference interviews — in-person interviews with listed references
• Relative interviews — interviews with spouses, partners, and adult family members
• Foreign contacts — counterintelligence database checks; potential follow-up investigation
• Social media review — in some cases, public social media content review
• Polygraph — for SCI indoctrination at most intelligence agencies

The subject interview

For Tier 5 investigations, the subject interview is typically conducted in-person and may last 2-4 hours. The investigator:

• Verifies SF-86 answers section by section
• Asks follow-up questions on any answer
• Probes for information not on the form (associates, activities, issues)
• Asks about recent events since SF-86 submission
• Evaluates demeanor, candor, and consistency

Preparation for the subject interview: review your SF-86 thoroughly; bring copies of supporting documents (for financial disclosures, treatment records if relevant, foreign travel records); be honest and direct; don't volunteer information not asked about unnecessarily; acknowledge uncertainty when you are unsure rather than guessing.

Continuous vetting automation

After clearance is granted, continuous vetting (CV) provides ongoing verification through automated checks against criminal, financial, and public records databases. CV has largely replaced periodic reinvestigation for Secret (10-year) and Top Secret (5-year) clearances. For detailed coverage, see Workplace Topic 35 on Continuous Vetting.

Section VII The PVQ transition

Under Trusted Workforce 2.0, the SF-86 is being replaced by the Personnel Vetting Questionnaire (PVQ). The transition is ongoing as of 2026.

Overview of the PVQ

The PVQ consolidates the three separate forms (SF-85, SF-85P, SF-86) into a single unified form with modular sections. Applicants complete only the sections relevant to their specific position tier. Key features:

• Modular structure — position-specific sections
• Modernized question formats and plain language
• Integration with NBIS for pre-population and validation
• Updated scope windows for some questions
• Gender-neutral language

Key changes from SF-86 to PVQ

Notable substantive changes in the PVQ:

• Marijuana questions — PVQ asks about marijuana use within past 90 days (vs. SF-86's 7-year window). Federal law on marijuana has not changed — use remains illegal federally regardless of state legalization.
• Mental health — PVQ focuses on hospitalizations and treatments within past 5 years rather than lifetime history
• Identifying information — PVQ removes gender, height, weight, hair color, and eye color fields
• Selective Service — PVQ removes Selective Service registration question (information available through other means)
• Gender-neutral language — throughout the form

Current deployment status

As of early 2026, the PVQ is not in full active use. DCSA is working to integrate the PVQ into the NBIS eApp platform. Full deployment is expected in 2026-2027 contingent on NBIS development completion. During the transition period:

• Most applicants continue to use the SF-86 through NBIS eApp
• Some pilot programs may use the PVQ
• Your agency's security office determines which form applies to your specific investigation
• Previously-submitted SF-86s remain valid for existing clearances

Preparing for either form

Whether you are completing the SF-86 or the PVQ, the underlying framework is the same. Preparation that supports accurate SF-86 completion also supports accurate PVQ completion:

• Gather the documentation described in Section II of this guide
• Maintain a personal reference document with your disclosure-relevant history
• Review prior filings if available
• Be prepared for the same SEAD 4 adjudicative guidelines regardless of form
• Understand that continuous vetting obligations under SEAD 3 apply regardless of form

Section VIII Frequently asked questions
