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. Repeated mirror releases of an unchanged publication are not treated as new observations. We do not interpolate missing values or predict an approval date.

Slower

The 80th-percentile processing time increased

5.0 months between February 16, 2026 and August 6, 2026. This is a historical comparison, not a forecast for an individual case.

The horizontal axis uses the USCIS publication date, so spacing reflects the actual interval between observations. Processing times are normalized to months only for visual comparison; the table preserves both percentile metrics in their source units.

Exact source 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, and links every dated release.

30- and 60-day views

Window comparisons use the nearest same-method USCIS publication only when it falls within 15 days of the target. The cards disclose the real interval and never interpolate.

30-day comparison

No same-method observation falls within 15 days of this target window. FillingTide does not stretch a distant data point into a 30-day claim.

60-day comparison

slower

+3.5 months

Compared with May 22, 2026, 54 actual days before the latest USCIS publication. No interpolation is used.

Source and provenance

USCIS is the underlying source. Because USCIS currently challenges routine automated requests, this launch dataset is ingested through the independently maintained daily mirror . Verify time-sensitive decisions on the official USCIS page. Read our data-source notes.

Understand this number

USCIS calculates the displayed processing time from the 80th percentile of recently completed cases. This page does not establish why it changed or how long an individual case will take.

Read the USCIS methodology

Case inquiry date

USCIS calculates inquiry eligibility from a separate 93rd-percentile threshold. The mirrored source lists April 23, 2025 as the current date for cases eligible to ask a question. Always use the official USCIS tool before making an inquiry.
