N-400 processing at Tucson, AZ

USCIS does not publish processing times per office. Nationally, N-400 (Civilian) filers can expect a decision in 8-16 months if they file today, going by USCIS’s median for Apr–Jun 2026. USCIS decided 64% fewer of these that quarter than its average over the four before, so plan for the later end. See the national N-400 range for each category.

Latest USCIS data: Apr–Jun 2026, from the N-400 by Category, Case Status, and USCIS Field Office Location report.

Quarter-over-quarter highlight: The pile of pending N-400 applications at the Tucson office grew 12% to 2,225 in Apr–Jun 2026. At that quarter's pace of decisions, clearing it would take 30 months, up from 26 months. Going by its average pace over the four quarters to Apr–Jun 2026, the Tucson office's backlog would take about as long to clear as, not clearly longer or shorter than, that of the country as a whole.

What happened to the applications

The bars are the N-400 decisions the Tucson office made each quarter, approved in blue and denied in red. The amber line is its backlog: how many applications were still waiting at the end of that quarter, most of them filed in earlier ones. The dashed line is how many came in.

Backlog over time

Time to clear backlog is how long the office would need to decide every pending case at last quarter’s pace. It is not your wait: the pile includes cases on hold and cases USCIS cannot decide yet, and USCIS sometimes moves pending cases between offices. A dashed line marks a quarter in which it did: the pile, and the time to clear it, then include the cases moved in (or leave out those moved away), so they don't show the office falling behind or catching up.
