N-400 naturalization processing times remain among the fastest since 2016
USCIS's May 2026 processing-time data shows naturalization continuing as one of the fastest-moving form types: a national median of roughly 5.5 months and a 93rd-percentile band in the 10–14 month range — the lowest sustained levels since 2016.

USCIS's processing-time refresh for May 2026 shows N-400 (Application for Naturalization) continuing the multi-year trend of meaningfully shorter times. The national median sits near 5.5 months and the 93rd-percentile band runs about 10–14 months depending on the field office.
This is a notable change from the 2021–2023 era, when N-400 medians frequently exceeded 12 months. Several factors are credited: the agency's 2024–2025 staffing and electronic-filing investments, broader use of online filing, and the residual reduction of pandemic-era backlogs at field offices.
Filers should still expect office-to-office variability — the median is a national figure, and a specific field office can sit well above or below it.
Why it matters here
If you're tracking an N-400, the CasePredictor ETA calculator will show this trend directly: the trend-line in the Trend & Context section will read 'faster' for naturalization across most field offices. The dashboard's form-comparison view also makes the gap between N-400 and other employment-based forms easier to see at a glance.
