USCIS processing times by field office: 30 major offices
Last updated 2026-10-02 · General information, not legal advice
USCIS publishes I-485 and N-400 processing times office by office, and the gap between offices is wide. Today a family-based I-485 runs from 8.5 months at Tucson AZ to 36 months at Seattle WA. These are 30 major field offices (chosen by an estimate of the population each serves, not a measured ranking), one page each: every category's 80% line and case-inquiry line today, the quarterly trend since 2022, the comparison with the median office, and when a case there can go to court. The numbers come from the USCIS page and refresh every week (2026-10-02 snapshot).

The threshold for a suit is set per form, in the guides: I-485, N-400, when you can sue. A published processing time is evidence a court weighs, never the test.
