What happens after you file your N-400
- 1USCIS sends a receipt notice confirming they got your application. Keep it — the receipt number is how you track your case.
- 2If USCIS needs your fingerprints or photo, they schedule a biometrics appointment. In many cases they reuse biometrics they already have.
- 3You are scheduled for an interview, where an officer reviews your application with you and gives the English and civics tests.
- 4USCIS then approves, continues (asks for more), or denies the application. If approved, the final step is the Oath of Allegiance ceremony — you become a citizen when you take the oath, not before.
