How to Get a Security Clearance

Disclaimer: This guide provides general information based on publicly available government sources. It is not legal advice and does not guarantee any particular outcome. Every case is evaluated individually. If you have specific concerns about your eligibility, consult with a qualified security clearance attorney.

A security clearance is how the U.S. government decides whether it can trust you with sensitive information[1].

Think of it this way: the clearance itself doesn't determine what job you'll do. A software engineer, an analyst, and a janitor at a classified facility might all hold the same clearance level. What the clearance determines is your trust level: can the government trust you with information or access to resources that, if mishandled, could damage national security?

The level of clearance (Confidential, Secret, or Top Secret) reflects how much potential damage could result from a breach. The higher the clearance, the more thorough the investigation to establish that trust.

You Need a Sponsor

You cannot apply for a security clearance on your own.

Unlike a driver's license or a professional certification, you can't just fill out an application and pay a fee. You need a sponsor: either a government agency or a contractor company that has a legitimate need for you to access classified information[2].

In practical terms, this means you need a job offer first. The government won't investigate you speculatively[1]. Your sponsor initiates the process, and the government pays for the investigation.

This means:

Eligibility Requirements

Before you can be granted a security clearance, you must meet basic eligibility criteria[9]:

U.S. Citizenship

You must be a U.S. citizen. The Director of National Intelligence may grant rare exceptions based on compelling national security needs, but these are extremely uncommon[1].

Need to Know

A clearance alone does not grant access to classified information. You must also have a demonstrated "need to know" based on your job duties[1]. This is why clearances are tied to specific positions.

No Automatic Disqualifiers

While there are very few absolute disqualifiers, certain factors make clearance approval unlikely. These include current illegal drug use, recent criminal activity, or demonstrated disloyalty to the United States. See our guide on automatic disqualifiers for details.

The Five Steps to Getting Cleared

Step 1: Get a Job Offer

The clearance process begins when a government agency or cleared contractor offers you a position requiring access to classified information[8]. This is typically a conditional offer, meaning employment depends on successfully obtaining your clearance.

For federal jobs, the hiring agency initiates your clearance through the appropriate channels.

For contractor positions, the company's Facility Security Officer (FSO) initiates your access to the application system[2].

Step 2: Complete the SF-86

You will complete Standard Form 86 (SF-86), titled "Questionnaire for National Security Positions," through the e-QIP (Electronic Questionnaires for Investigations Processing) system[3][7].

The SF-86 is comprehensive. You'll provide detailed information covering the past 7 to 10 years (depending on the question) including:

The government estimates the SF-86 takes approximately 150 minutes to complete[3]. In practice, gathering all the required information often takes longer.

Critical warning: Knowingly falsifying or concealing information on the SF-86 is a federal felony punishable by fines and up to five years imprisonment[3]. Always be truthful, even about unfavorable information. Honesty about past mistakes is viewed more favorably than attempted concealment.

Step 3: Background Investigation

The Defense Counterintelligence and Security Agency (DCSA) conducts background investigations for most DoD and contractor clearances[5]. Other agencies may conduct their own investigations.

What investigators check:

The investigation depth depends on the clearance level:

Clearance Level Investigation Type Typical Scope
Confidential/Secret Tier 3 (NACLC) Database checks, limited interviews
Top Secret Tier 5 (SSBI) Extensive fieldwork, multiple interviews

During the investigation, you may be granted interim clearance if initial checks are favorable. This allows you to start work while the full investigation continues.

Step 4: Adjudication

After the investigation, an adjudicator reviews the findings to determine whether granting you a clearance is "clearly consistent with the interests of national security"[6].

Adjudicators evaluate your case against 13 guidelines established in Security Executive Agent Directive 4 (SEAD-4)[4]:

  1. Allegiance to the United States
  2. Foreign Influence
  3. Foreign Preference
  4. Sexual Behavior
  5. Personal Conduct
  6. Financial Considerations
  7. Alcohol Consumption
  8. Drug Involvement and Substance Misuse
  9. Psychological Conditions
  10. Criminal Conduct
  11. Handling Protected Information
  12. Outside Activities
  13. Use of Information Technology

The adjudicator uses a "whole person" concept, weighing potentially disqualifying factors against mitigating circumstances. Having an issue in one area does not automatically disqualify you. Factors like the recency of the issue, evidence of rehabilitation, and honesty during the process all matter.

Approximately 75% of security clearance denials involve financial considerations, personal conduct, or foreign influence issues.

Step 5: Clearance Granted (or Denied)

If adjudication is favorable, you receive your clearance and can access classified information at the appropriate level for your position.

If denied, you have appeal rights. You can request reconsideration and present additional information. For DoD clearances, the Defense Office of Hearings and Appeals (DOHA) handles appeals, where you can present your case before an administrative judge.

How Long Does It Take?

Processing times vary based on clearance level and individual circumstances[5]:

Clearance Level Average Timeline
Secret 4-6 months
Top Secret 8-12 months
Interim (if granted) 30-90 days

Factors that can extend timelines:

The fastest way through the process is submitting a complete, accurate SF-86 the first time.
