N-400 Citizenship Timeline: From Filing to Oath in 2026
Each step of the N-400 naturalization process in 2026, with typical waits for biometrics, interview, and the oath ceremony.
Filing Form N-400 is the last big step toward US citizenship, and in 2026 it is also one of the faster forms USCIS handles. The national median is around 5 to 7 months from filing to decision, though your local office matters a lot.
Step 1: Receipt and biometrics
After you file, USCIS sends a receipt notice (Form I-797) within a couple of weeks. Then most applicants get a biometrics appointment, often within the first month or two, where USCIS takes fingerprints and a photo. Some applicants have biometrics reused from an earlier filing and skip this.
Step 2: The interview
The interview is the part most people wait on. You take the civics and English tests and an officer reviews your application. In 2026, the wait from filing to interview at busy offices can stretch the timeline toward the longer end of that 5 to 7 month median.
Step 3: The oath ceremony
If approved, you take the Oath of Allegiance. Some offices do same-day oaths right after the interview. Others schedule a separate ceremony weeks later. Only after the oath are you a citizen, which matters if you were planning to file Form N-600 for a child or sponsor a relative.
How N-400 connects to N-600
If you naturalize and have a child who is already a permanent resident, that child may automatically become a citizen. Form N-600 (Certificate of Citizenship) documents it, and that form runs much slower, around 9 to 11 months in early 2026. So plan ahead if you need proof of a child's citizenship for a passport.
A few things that quietly add time
The 5 to 7 month median assumes a clean case. A few things stretch it. If your fingerprints flag a name match, background checks take longer. If an officer asks for more documents through a Request for Evidence, the clock pauses while you respond. Moving to a new address mid-case can also reroute your file to a different office with a different queue. None of these mean trouble, but they explain why two neighbors who filed the same week can finish months apart.
