Frequently asked questions
How long does naturalization take from filing to oath?
Most applicants wait between six months and a little over a year from filing Form N-400 to taking the Oath of Allegiance, depending on their local USCIS field office workload. Check current processing times for your office on uscis.gov.
Can I file my N-400 before I reach 5 years with a green card?
Yes — USCIS accepts N-400 applications filed up to 90 days before you complete your required 5 years (or 3 years if married to a U.S. citizen) of permanent residence.
What happens between filing and the interview?
After filing you'll get a receipt notice, then a biometrics appointment (fingerprints and photo, usually within 1–2 months). USCIS then reviews your case and schedules your naturalization interview, where you take the civics and English tests.
