The US citizenship application processing time currently runs a median of 6.4 months for civilian applicants and 3.2 months for military applicants filing Form N-400 in fiscal year 2026.1U.S. Citizenship and Immigration Services. Historic Processing Times Half of cases finish faster than that, half take longer, and the field office handling your case matters more than any national figure. Some offices decide cases in under six months. Others post times well past a year.
What the Posted Processing Time Actually Means
USCIS publishes its estimates using an 80th-percentile metric. A posted time of nine months means 80 out of every 100 cases at that office were decided within nine months over the previous six months of data. The remaining 20 percent took longer.2U.S. Citizenship and Immigration Services. More Information About Case Processing Times That is the number to plan around, because it already absorbs routine delays that a straight average would hide.
Look up your own office’s estimate on the USCIS processing times page by selecting Form N-400 and choosing your field office. If you don’t know which office serves you, the USCIS Field Office Locator identifies it from your ZIP code.2U.S. Citizenship and Immigration Services. More Information About Case Processing Times Offices in dense metro areas routinely post times several months longer than smaller ones, so the national median can be a poor guide to your personal wait.
What Happens During Those Months
The total processing time is the sum of several distinct phases, and most of the waiting sits between them rather than inside any single step.
Receipt and Biometrics
After USCIS accepts your application, you receive a receipt notice with a 13-character case number. If biometrics are required, an appointment notice with the date, time, and location follows, usually within a few weeks of filing.3U.S. Citizenship and Immigration Services. Naturalization: What to Expect Your fingerprints are run through FBI databases, and those background checks must clear before an interview can be scheduled.
The Wait for an Interview
The gap between biometrics and the interview is where most of the total time is spent. Depending on your field office’s backlog, it can range from a few months to well over six. At the interview, a USCIS officer reviews your application, verifies your identity, tests your English, administers the civics questions, and evaluates whether you meet the good moral character requirement.
You can file up to 90 days before you meet the five-year continuous residence requirement, or the three-year period if you’re applying based on marriage to a US citizen.4U.S. Citizenship and Immigration Services. Chapter 6 – Jurisdiction, Place of Residence, and Early Filing USCIS will accept and begin working the case immediately, though approval has to wait until you actually hit the required residency period. Filing early can shave a couple of months off your total wait.
The Decision
Most applicants get a decision at the interview itself or within a few weeks after. If USCIS fails to decide within 120 days of your examination, federal law gives you the right to petition the district court to intervene.5Office of the Law Revision Counsel. 8 U.S.C. 1447 – Hearings on Denials of Applications for Naturalization The 120-day clock runs from the date of your interview.
The Oath Ceremony
Approval isn’t the end. You still need to take the Oath of Allegiance to become a citizen. Some field offices offer same-day oath ceremonies right after a successful interview.6U.S. Citizenship and Immigration Services. Naturalization Ceremonies If not, USCIS mails Form N-445 with your ceremony date, usually a few weeks out but sometimes longer.
If you request a name change through naturalization, a federal judge has to administer your oath, because USCIS lacks authority to change names. The court’s ceremony calendar is not controlled by USCIS, which can add weeks or months.7U.S. Citizenship and Immigration Services. Commonly Asked Questions About the Naturalization Process
What Can Slow Your Case Down
The posted time assumes nothing goes wrong. Several things pull cases outside that window.
Requests for Evidence
If your application is missing documents or the evidence you provided doesn’t establish eligibility, USCIS issues a Request for Evidence. You get up to 12 weeks to respond, or 30 days if the notice is an intent to deny.8eCFR. 8 CFR 103.2 – Submission and Adjudication of Benefit Requests Common requests involve tax transcripts, court dispositions, marriage certificates, and selective service records. While you’re gathering documents, the processing clock effectively pauses. A thorough initial filing is the single best defense against this delay.
Background Check Holds
FBI name checks flag any case where an applicant’s name matches or resembles a name in federal databases. When that happens, the file is routed to manual review for identity resolution. USCIS will not schedule the interview until the checks clear. There is no published timeline for how long manual review takes. Some resolve in weeks, others in months. If your case is stuck here and 120 days have passed since your examination, the 8 U.S.C. 1447(b) petition is the leverage available to you.5Office of the Law Revision Counsel. 8 U.S.C. 1447 – Hearings on Denials of Applications for Naturalization
Disability Waiver Complications
Applicants with a qualifying medical condition can request a waiver of the English and civics testing requirements using Form N-648, signed by a licensed medical professional. It doesn’t add a formal step, but it adds complexity at the interview: the officer has to evaluate whether the certification is valid and complete. Late filings or multiple submissions from different doctors tend to trigger closer scrutiny, and inconsistencies between forms can lead the officer to find the certification insufficient, though you get a chance to explain before that determination is made.9U.S. Citizenship and Immigration Services. Chapter 3 – Medical Disability Exception (Form N-648)
Tracking Your Case and Pushing Back on Delays
Enter your 13-character receipt number in the USCIS Case Status Online tool for the most recent action on your case.10U.S. Citizenship and Immigration Services. Checking Your Case Status Online A myUSCIS account gives you a more detailed view with estimated completion windows that adjust as things move.
If your case has been pending longer than the posted time for your office, you can submit a case inquiry through the USCIS e-Request portal. The system checks your receipt date against posted times to see if you qualify to submit.11U.S. Citizenship and Immigration Services. Check Case Processing If USCIS took any action on your case in the last 60 days, such as sending a notice, requesting evidence, or updating your online status, the agency considers your case actively in process and may reject the inquiry.
When e-Request produces nothing useful, contacting your congressional representative is the next practical step. A representative’s office can submit an inquiry to the USCIS Congressional Liaison Office, which generally responds within 30 business days. It won’t move you ahead in line, but it puts a congressional office on record.
For severe delays, USCIS accepts expedite requests under limited criteria: severe financial loss, urgent humanitarian situations, government interests involving public safety or national security, and clear USCIS error.12U.S. Citizenship and Immigration Services. Chapter 5 – Expedite Requests Routine frustration with processing speed will not qualify.
Two Things That Can Undo Your Timeline
Travel abroad while your N-400 is pending is allowed, but extended absences create real risk. A single trip of more than six months but less than a year creates a legal presumption that you broke continuous residence, and you carry the burden of rebutting it. A trip of one year or more breaks continuous residence outright, with narrow exceptions for certain government and corporate employees.13Office of the Law Revision Counsel. 8 U.S.C. 1427 – Requirements of Naturalization Also, you must be in the country for any scheduled biometrics or interview appointment. If you move during processing, federal law requires you to report your new address to USCIS within 10 days, and a move to a different city can transfer your case to a new field office with a different backlog.14U.S. Citizenship and Immigration Services. How to Change Your Address
Missing your interview is the fastest way to lose your application entirely. If you skip the appointment and don’t contact USCIS within 30 days to explain why, an officer can administratively close the case without deciding it on the merits.15U.S. Citizenship and Immigration Services. Chapter 4 – Results of the Naturalization Examination You can request that a closed case be reopened within a year, but after that the application is treated as abandoned and dismissed, with no refund of your filing fee. If you know in advance you can’t make the appointment, reschedule before the date rather than trying to explain a no-show after.
