I-129F Median Hits 12-Week High While RFE Cases Clear at Record Pace

The I-129F median for the week of May 18 came in at 198 days, the highest point across the prior 12 weeks and a jump of 18 days from the 181-day reading the week before. That single-week move is the largest week-over-week increase in the 12-week window. Yet the same week produced a countervailing signal: an `rfe_fast` anomaly flag fired, indicating that cases with an RFE (Request for Evidence) on file cleared with a median of just 18 days, while cases moving through plain processing sat at 227 days. Both numbers are accurate, but they describe two different populations flowing through the same pipeline at the same time.

Two populations, two different readings

Over the 12 weeks from early March through May 18, the I-129F final-stage median has ranged from 144 days (W17, the week of April 13) to 207 days (W18, the week of April 20), a spread of 63 days. W22's 198-day reading is elevated, but W18 reached 207 days just five weeks earlier before reverting to 155 days in W19. The 8-week regression slope is +1.0 day per week, which would normally suggest a modest upward drift, but the R² of 0.01 means the regression line explains essentially none of the week-to-week variation. Year-over-year comparison data is not available for this 12-week window.

An R² of 0.01 signals that the weekly medians are oscillating around a rough average rather than moving in a consistent direction. Weekly samples have ranged from about 353 cases in W15 to roughly 724 in W12, so sample-size variation may itself contribute to the week-to-week scatter. A single week at 198 days is consistent with the pattern of wide swings in this series; it is not, on its own, evidence of a new trend.

The `rfe_fast` flag describes a specific inversion: cases where a Response to a Request for Evidence was received cleared with a median of 18 days this week, against 227 days for cases that had no RFE on file. Under normal conditions, RFE cases take longer because the adjudicator (the USCIS decision step where approval, denial, or an evidence request is issued) must review a response before acting. When RFE-stamped cases clear faster than plain-processing cases, one possible explanation is that a group of RFE responses submitted around the same earlier period were reviewed and approved together in the current week, a batch effect. The data brief does not confirm this mechanism directly; it is one of several possibilities, and a single week is too short a window to draw a firm conclusion.

The stage duration data offers context on the non-RFE side. The largest single group of active cases, 43.7% of the pipeline, sits at 'Case Was Received' with a median of 239 days already elapsed, a 25th percentile (p25) of 224 days and a 75th percentile (p75) of 267 days across 22,828 cases in the 30-day window. That population appears to be pulling the non-RFE median upward. By contrast, the RFE-response group, 7.2% of active cases, shows a median of only 23 days at that stage across 3,779 cases in the same 30-day raw data, broadly in line with the weekly `rfe_fast` signal.

An 18-day RFE clearance median reflects a fast-moving subset; the non-RFE queue at 227 days shows where the bulk of cases are actually waiting.
