How long a federal background check takes depends entirely on which check you mean. A firearm purchase check through the FBI’s National Instant Criminal Background Check System usually comes back in minutes. An FBI Identity History Summary for personal or employment use takes a few weeks. A federal employment suitability or public trust investigation runs one to six months. A security clearance for access to classified information is the longest, averaging roughly four and a half months for Secret and over eight months for Top Secret, with complex cases stretching past a year.
Firearm Purchase Checks: Minutes, Sometimes Days
If you are buying a firearm from a licensed dealer, the check runs through the FBI’s National Instant Criminal Background Check System. In 2024, NICS handled over 28 million firearm-related checks and returned an immediate result for about 92% of them.1FBI. 2024 NICS Operational Report The dealer gets one of three answers while you are still at the counter: proceed, delayed, or denied.2eCFR. 28 CFR 25.6 – Determination of Eligibility
A delayed response means the FBI found a record that needs more research. Federal law then gives the FBI three business days to make a final call. If those days pass without an answer, the dealer may legally complete the transfer, though some choose to wait longer as store policy.3Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts The FBI keeps working delayed cases for up to 88 days.
In 2024, about 94.7% of FBI-processed checks resulted in a proceed, 1.1% were denied outright, and the remaining 4% or so were delayed, unresolved, or canceled.1FBI. 2024 NICS Operational Report Some states route firearm checks through their own point-of-contact systems instead of the FBI, and timelines in those states can differ.
FBI Identity History Summary: A Few Weeks
If you need a record of your own federal criminal history for a job, immigration application, adoption, or professional license, you can request an FBI Identity History Summary. It is a fingerprint-based search of the FBI’s criminal database, and it costs $18. You can submit electronically, mail the request directly to the FBI, or use an FBI-approved third-party channeler.
The FBI does not publish a specific turnaround time and processes requests in the order received. Electronic submissions typically come back within a few weeks. Mailed requests can take considerably longer. There is no expedited option. If your summary contains errors and you file a challenge, the FBI’s average response time is about 45 days from receipt.4FBI. Identity History Summary Checks FAQs
Federal Employment and Public Trust Checks: One to Six Months
When you apply for a federal job that does not involve classified information, you go through a suitability or public trust determination. These checks evaluate your character and conduct to decide whether employing you would protect the integrity of the federal service.5Office of Personnel Management. Taking Adverse Actions Based on Suitability or Security Issues The position’s risk level drives the depth of investigation and, with it, the timeline.
Low-risk positions generally complete in one to three months. Moderate-risk public trust positions, such as those involving access to sensitive financial or personnel data, more commonly take three to six months. High-risk public trust roles can stretch to six months or longer. These ranges shift with agency workloads, staffing, and the complexity of your personal history. The sponsoring agency pays for the investigation; you will not receive a bill.
Security Clearances: Months to a Year or More
Security clearances take the longest because the investigation goes deepest. They are required for positions with access to classified national security information at the Confidential, Secret, or Top Secret level.5Office of Personnel Management. Taking Adverse Actions Based on Suitability or Security Issues
As of late 2024, Secret clearances averaged about 138 days (roughly four and a half months) and Top Secret clearances averaged about 249 days (over eight months), measured at the 90th percentile of completed cases.6U.S. House Committee on Oversight and Accountability. Hearing Wrap Up – DoD Must Finish Long-Overdue Background Check IT System Mid-2025 reporting put the overall end-to-end average, across all tiers, at around 243 days. The government’s own assessment of its vetting reform effort rated progress on getting people to work faster as “poor” heading into 2026.7Performance.gov. FY26 Q1 Personnel Vetting Quarterly Progress Report
Averages mask wide variation. A straightforward case, someone who has lived and worked in the same area with no foreign ties or financial red flags, can move considerably faster. A complex case involving extensive foreign travel, overseas contacts, or financial problems can drag well beyond the averages.
The process starts after you accept a conditional job offer. Your sponsoring agency gives you access to eApp, the electronic system that replaced e-QIP in October 2023, and you complete the SF-86 (for security clearances) or the SF-85/85P (for public trust).8Defense Counterintelligence and Security Agency. DCSA Announces Full Transition to NBIS eApp The Defense Counterintelligence and Security Agency or another authorized investigative agency then verifies your information through database checks and interviews with you, your references, former coworkers, and sometimes neighbors or family. A Top Secret investigation sweeps wider than a Secret one. After that, an adjudicator reviews the full file and grants or denies the clearance. If serious new information surfaces during adjudication, the case can be sent back for more investigation, adding time.
Deliberately providing false information on the SF-86 is a federal felony punishable by up to five years in prison.9Office of Personnel Management. Standard Form 86 – Questionnaire for National Security Positions
What Slows a Clearance Down
The single most common cause of delay is an incomplete or inaccurate application. The SF-86 asks for 10 years of employment history and residences plus seven years of foreign travel.9Office of Personnel Management. Standard Form 86 – Questionnaire for National Security Positions Gaps, missing addresses, or vague dates force investigators to chase information you could have supplied upfront. Unclear fingerprints have to be resubmitted.
Beyond paperwork, certain parts of your history trigger deeper inquiries and longer timelines:
- Significant ties to foreign nationals or extensive overseas travel generate additional work under the foreign influence and foreign preference guidelines.10eCFR. 32 CFR Part 147 – Adjudicative Guidelines for Determining Eligibility for Access to Classified Information
- A pattern of missed financial obligations, unexplained affluence, or debt linked to gambling or substance abuse raises concerns about vulnerability to coercion. No specific dollar threshold triggers automatic denial; adjudicators evaluate the overall pattern.10eCFR. 32 CFR Part 147 – Adjudicative Guidelines for Determining Eligibility for Access to Classified Information
- Past arrests, convictions, or ongoing legal issues require verification and assessment.
- Drug use, including marijuana, remains a security concern under federal rules even in states where marijuana is legal. Reclassification of marijuana from Schedule I to Schedule III has not changed this.
Third-party responsiveness also matters. Former employers, landlords, and personal references who are slow to return investigators’ calls can add weeks or months. Giving your references a heads-up once you know your investigation is underway can help.
Interim Clearances: Starting Work Sooner
Because full investigations take so long, many agencies grant interim clearances so you can start working while the process continues. An interim Secret or Top Secret clearance can be granted within about 5 to 10 days after your sponsoring agency receives a properly completed SF-86, assuming the preliminary records check turns up nothing disqualifying.11Department of the Army G-2. Adjudicative Processes
An interim clearance does not guarantee final approval. It lets you access classified information at the appropriate level while the full investigation proceeds, and it can be withdrawn at any time if concerning information surfaces. Your continued employment depends on the completed investigation and adjudication.
If You Already Hold a Clearance
If you already hold an active clearance and move to a different federal agency or contractor, you generally do not need a new investigation. Under Security Executive Agent Directive 7, agencies must accept background investigations and clearance decisions made by other authorized agencies at the same level or higher.12Office of the Director of National Intelligence. SEAD 7 – Reciprocity of Background Investigations and National Security Adjudications
Reciprocity does not apply if your most recent investigation is more than seven years old, if your clearance was granted on an interim or temporary basis, if your eligibility is suspended or revoked, or if new security-relevant information has emerged since your last investigation.12Office of the Director of National Intelligence. SEAD 7 – Reciprocity of Background Investigations and National Security Adjudications When reciprocity does apply, the receiving agency cannot make you fill out a new SF-86 or sit through a fresh investigation. It may ask you to identify any changes since your last submission, and that is the extent of it.
