How this was calculated
- USCIS published these ranges on September 17, 2026. The upper figure is the time within which USCIS completed 80% of cases; the lower one is the median.
- The national average is a different measure: all cases completed in the month, from receipt to decision, as reported to Congress.

Phoenix is one of the faster USCIS field offices in the country for naturalization: USCIS publishes 12 to 13 months for Form N-400 there, rank 11 of 90, and the range is unusually narrow, which means cases finish at similar speeds. For family-based Form I-485 it publishes 14 to 24.5 months, rank 19, also in the faster quarter. Tucson, which serves southern Arizona, publishes 12 to 14 months for the N-400 and only 8.5 to 13.5 months for the family I-485, rank 2 nationally. In our first 2022 record Phoenix published 7.5 to 15.5 months for naturalization and 7.5 to 21 months for family adjustment. USCIS accepts Phoenix inquiries for N-400 receipts dated on or before September 12, 2025 and family I-485 receipts on or before October 4, 2024, according to its publication of September 17, 2026. The upper figure in each range is the 80% mark.
A narrow range
Most offices publish a wide spread between their median and their 80% mark. Phoenix’s naturalization spread is about 1 month, so the published range is close to a real estimate for a typical file. The family green card spread is wider, at 10.5 months.
Since 2022
The two Phoenix queues moved in opposite directions. At the upper bound, naturalization has changed by -2.5 months since our first record, while family adjustment has changed by +3.5 months: citizenship got quicker, the family green card slower.
Checking your date
Enter the receipt date from your I-797C notice in the checker above. If you belong to a family preference category, look at your priority date as well: USCIS cannot approve the green card before the Visa Bulletin shows your date as current, however quick the office is.
Arizona’s second office
Tucson is not only quick for families: at rank 2, it is among the very fastest offices in the country for family-based adjustment, and its naturalization range of 12 to 14 months is close to Phoenix. USCIS assigns Arizona addresses to one of the two offices; the interview or biometrics notice names the one that holds your file, and that is the range to compare against.
