What happens at a USCIS field office interview?

N-400 (Citizenship)

The officer tests your English (reading and writing), asks 10 civics questions (you need 6 correct), and reviews your application history. Typically 20-45 minutes.

A separate appointment (usually before the main interview) to collect fingerprints, photo, and signature. Takes about 10-15 minutes.

Interview preparation tips

  • 1Arrive 15-20 minutes early. Security screening takes time and late arrivals may need to reschedule.
  • 2Bring original documents plus photocopies of everything. Officers keep copies but want to see originals.
  • 3Review your application before the interview — know the dates, addresses, and facts you submitted.
  • 4Bring your spouse or family members named in your petition if requested on your notice.
  • 5Answer questions honestly and concisely. Don't volunteer extra information not asked for.
  • 6If you don't understand a question, it's okay to ask the officer to repeat or clarify.
  • 7Don't guess. If you don't know something, say so — don't make up an answer.
  • 8Bring an interpreter if needed, but the interpreter cannot be your attorney.
