Too early for a case inquiry.
| Published range, Denver, CO | 14.0 to 18.0 months |
|---|---|
| Time since your receipt date | 12.4 months |
| USCIS takes inquiries for receipts on or before | April 21, 2025 |

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.

USCIS publishes 14 to 18 months for Form N-400 at the Denver field office, rank 72 of 90, and 22.5 to 39.5 months for family-based Form I-485, rank 76. Both are longer than in our first record, from March 14, 2022, when the office published 9 to 16 months for naturalization and 11.5 to 23.5 months for family adjustment: the upper bounds have moved by +2 and +16 months. Other Mountain West offices publish shorter family green card ranges at the moment: Salt Lake City 15 to 21.5 months and Albuquerque 13.5 to 28 months. For naturalization, Salt Lake City shows 13.5 to 16 months and Albuquerque 13 to 17.5 months. USCIS accepts Denver case inquiries for N-400 receipts on or before April 21, 2025 and family I-485 receipts on or before July 5, 2023, according to its publication of September 17, 2026.
Both queues longer
Denver is one of the offices where the 80% mark has grown for citizenship and for family adjustment alike. The family green card queue is now 21.5 months longer than the naturalization queue at the upper bound.
The neighbors
Salt Lake City ranks 12 and Albuquerque 28 for family adjustment, both well ahead of Denver at 76. For naturalization the three are closer, between ranks 53 and 72.

Colorado and Wyoming
The Denver office serves a large area, from the Front Range to rural counties hours away. Its family green card range has grown more than its naturalization range since 2022, and it now sits in the slowest fifth of the country for family adjustment. Salt Lake City, by contrast, has seen its family upper bound fall over the same period, from 14.5 to 24 months to 15 to 21.5 months.
