N-400 Processing Time in 2026: Citizenship Timeline by Field Office

Published April 5, 2026 · USImmigrationLaw.Today

How Long Does Naturalization Take in 2026?

The average N-400 naturalization processing time in 2026 is approximately 8-15 months from filing to oath ceremony. However, this varies dramatically by USCIS field office — some offices process cases in under 6 months, while others take over 18 months. Your location is the single biggest factor in how long your citizenship case takes.

Fastest Field Offices (Under 8 Months)

Historically faster offices include Anchorage AK, Boise ID, Helena MT, Portland ME, Salt Lake City UT, and several mid-sized offices in the Midwest. These offices have smaller caseloads relative to their staffing levels, resulting in faster scheduling of interviews and oath ceremonies. If you live near one of these offices, you may complete the entire process in 5-8 months.

Slowest Field Offices (12-18+ Months)

The slowest offices are typically in major metropolitan areas with large immigrant populations: New York City (14-20 months), Los Angeles (12-18 months), Miami (12-16 months), Houston (10-16 months), and Chicago (10-15 months). These offices handle enormous volumes of N-400 applications and face chronic staffing shortages. Online filing may help prioritize your case at these offices.

Timeline Breakdown: Step by Step

Filing to receipt: 1-2 weeks (instant for online filing). Receipt to biometrics: 3-6 weeks. Biometrics to interview: 3-12 months (this is the variable step — depends on field office backlog). Interview to oath: Same day (some offices administer oath immediately) or 1-3 months for a scheduled ceremony. Oath to passport application: You can apply for your U.S. passport the same day you take the oath.

How to Avoid Delays

File online at my.uscis.gov (faster processing than paper). File exactly 90 days before you meet the residence requirement — no earlier (will be rejected) and no later (delays your timeline). Complete the N-400 accurately — errors and inconsistencies lead to RFEs. Attend your biometrics appointment (missing it causes major delays). Bring all required documents to your interview. If your case is taking longer than posted processing times, submit a case inquiry through your USCIS online account or contact the USCIS Contact Center.

Check your office: Look up current processing times for your specific field office at egov.uscis.gov/processing-times. Select Form N-400 and your field office. The posted time is for the middle 80% of cases — some take longer.
