How long does naturalization take in 2026?

2 min read · April 20, 2026

Most N-400 cases close within 7–11 months from filing to oath ceremony, but processing times vary by USCIS field office from 6 months in Phoenix to 14+ months in San Francisco.

Naturalization processing times in 2026 are dictated almost entirely by the USCIS field office that adjudicates the Form N-400. The statute itself (INA § 316) sets eligibility, not timing — USCIS publishes per-office processing data monthly, and the variation across offices is substantial.

2026 median processing times by relevant field office

• Phoenix, AZ — 6.0 to 8.5 months
• Mesa-Phoenix application support center — same range as Phoenix
• Sacramento, CA — 8.0 to 10.5 months
• San Francisco, CA — 12.0 to 14.5 months
• San Bernardino, CA — 9.0 to 11.0 months
• Las Vegas, NV — 7.0 to 9.0 months

These are median times: roughly half of cases close faster, half slower. Online filings are typically 1–2 months faster than paper, and biometrics is now reused automatically from prior submissions in most cases (no separate biometrics appointment, which used to add 6–8 weeks).

The pieces that actually drive timing

1. Initial USCIS receipt and review (4–8 weeks).
2. Biometrics processing (now usually waived/reused).
3. Background check completion — the FBI name check is the long pole in the tent for applicants from certain countries.
4. Interview scheduling — varies most by field office and is the biggest variable.
5. Decision and oath scheduling — typically 4–10 weeks after a successful interview.

Why filing early matters more than ever

The N-400 can be filed 90 days before the 5-year (or 3-year, for spouses of citizens under INA § 319(a)) continuous-residence anniversary. Filing on the first eligible day of the 90-day window adds nothing to processing time but advances the oath ceremony by up to three months. For applicants who want to vote in the next federal election, register a U.S. citizen child for benefits, or sponsor a parent who is aging or ill, those three months can matter.

Election-year acceleration

USCIS historically accelerates N-400 adjudication ahead of presidential election years. With November 2028 on the horizon, applicants who file in 2026 are likely to swear in well before the cycle's voter-registration deadlines.

How we handle this

We pull the applicant's full immigration record before filing — every prior application, every form ever submitted, every arrest, every entry/exit. The most common cause of slow N-400 processing is not USCIS — it is an RFE that surfaces an old discrepancy the applicant did not know was in the file. We pre-empt those by addressing them in the cover letter on the day of filing. The 7-month case is rarely the 7-month case by luck.
