USCIS processing times
N-400 processing time at the Tucson, AZ field office
The current processing time for naturalization applications at the Tucson, AZ field office, and every change USCIS has published since May 2022.
USCIS last updated this figure on Sep 17, 2026: 80% of N-400 naturalization applications at the Tucson, AZ field office were decided within 12 months, and 93% within 14 months. Both numbers come from cases USCIS finished over the previous six months, so they describe how long recent applicants waited, not a deadline for your case.
Tucson, AZ ranks 39th of 90 field offices, where 1st is the fastest. The median office is at 12.5 months. That puts Tucson, AZ 0.5 months faster than the median.
A year ago, on Oct 16, 2025, the figure was 8 months. It's up 4 months since. Since USCIS moved to the 80% measure in May 2022, Tucson, AZ has ranged from 7.5 months (Nov 2024) to 19.5 months (Nov 2022).
You can ask USCIS about a case once it's older than the 93% figure. As of Oct 16, 2026, that meant a receipt date before Aug 26, 2025. The cutoff moves forward about a day per day as long as the 93% figure holds.

FAQ
Common questions
How long does an N-400 take at the Tucson, AZ field office?
As of USCIS's Sep 17, 2026 update, 80% of N-400 naturalization applications at Tucson, AZ were decided within 12 months and 93% within 14 months. Both are measured on cases completed over the past six months.
When can I submit a case inquiry at Tucson, AZ?
When your receipt date is before Aug 26, 2025 (as of Oct 16, 2026). Use USCIS's e-Request tool for cases outside normal processing time. The date moves forward roughly a day per day.
Is Tucson, AZ faster or slower than other offices?
It ranks 39th of 90. The median field office is at 12.5 months; the fastest is Cranbury, NJ at 9 months and the slowest is Lawrence, MA at 18 months.
Can I move my case to a faster office?
Not by choice. Your home address decides the field office. If you actually move, update your address with USCIS, and the case may be transferred to the office that serves the new address.
How often does USCIS update these numbers?
USCIS says monthly. Since May 2022 the 80% figure for Tucson, AZ has changed 22 times.
Why does the history start in May 2022?
That's when USCIS switched its headline figure to the 80% measure. Before May 6, 2022 the smaller published number was the median, so earlier values aren't comparable.
USCIS processing times
What the two numbers mean
USCIS publishes two figures for each office. The headline one is how long it took to decide 80% of the cases completed over the last six months. The second is the 93% mark: once a case is older than that, USCIS treats it as outside normal processing time and lets you submit a case inquiry. The "receipt date for a case inquiry" USCIS shows is today minus that 93% figure.
Both describe cases USCIS already finished. They read recent throughput at that office. They're not a promise about your case.
Sources and method
Where these numbers come from
Every figure is USCIS's own, from its Case Processing Times tool. USCIS shows only today's number and overwrites it when it changes. It keeps no history.
The history comes from the open jzebedee/uscis project, which has saved a copy of USCIS's processing-time data every day since March 2022. We read that archive daily and string each office's and category's changes into one timeline.
On May 6, 2022 USCIS switched its headline number from the median to the 80% measure, so the 80% history starts that day.
