Context, not a case prediction
These aggregate figures describe completed cases and are a reference point only. An individual case can take more or less time.
How the 80% processing time changed
FillingTide compares the same form, category, and office across dated USCIS publications. An unchanged publication is not counted as a new observation. We do not interpolate missing values or predict an approval date.
The 80th-percentile processing time increased
0.5 months between February 16, 2026 and September 2, 2026. This is a historical comparison, not a forecast for an individual case.
Dated processing-time history
The chart uses only the 80th-percentile processing time. The table keeps that value separate from the 93rd-percentile threshold USCIS uses to calculate case inquiry eligibility.
