I-129F Wait Hits 12-Week High as Backlog Grows and Zero 2026 Cases Clear

This week's median of 211 days arrives after a single-week jump of 30 days from last week's 181 days, a move that puts the reading 36 days above the 12-week trailing average of 175 days. An earlier high of 207 days appeared the week of April 20, but that reading was followed immediately by a pullback to 155 days the following week. This week's reading is different in one structural respect: it arrives at the steepest point of an 8-week upward arc rather than at a local peak with flat surroundings, so a comparable one-week reversal cannot be assumed.

The 12-week window spans a wide range, from 144 days in mid-April to 211 days this week, but the directional tilt upward since that April low is visible. One additional detail in this week's data: the 25th percentile (p25) sits at 209 days and the 75th percentile (p75) at 216 days, an interquartile range (the spread between p25 and p75, sometimes called the IQR) of just 7 days. In prior weeks the band was far wider — the week of March 30, for instance, ran from 162 to 246 days. The narrow clustering this week suggests that a concentrated group of cases of similar age cleared together, rather than a broad cross-section of the full queue advancing.

The 8-week regression slope for I-129F stands at +5.8 days per week, which implies the median (the 50th percentile, where half of cases clear faster and half slower) has added roughly 46 days of final-stage wait over the past 8 weeks taken together. That pace is worth tracking, but the R² of 0.31 requires a direct caveat: the regression explains only about a third of the week-to-week variation. The direction appears consistent, but the magnitude in any given week is volatile enough that the trend line should be read as a general signal rather than a precise forecast.

The stage durations table (30-day raw window, across roughly 55,800 cases observable in that period) shows where the pipeline is congested. Cases at the 'Case Was Received' stage — about 43% of all observable cases, across 24,075 cases — show a raw median of 239 days, with a 25th percentile of 224 days and a 75th percentile of 268 days. Another 33% of observable cases sit at 'Case Was Approved,' with a median of 48 days in post-approval processing across 18,597 cases. The primary bottleneck is in the received queue, where cases are accumulating before the adjudication (the USCIS case-decision step where approval, denial, or a request for more information is issued) step is reached.

Alongside the broader slowdown, this week carries an unusual signal. Cases that received an RFE (Request for Evidence, USCIS's standard letter asking for missing documents) and submitted a response are clearing with a median of just 17 days — compared with 230 days for cases processed without an RFE. That ratio of roughly 13 to 1 is what triggered the `rfe_fast` anomaly flag in the data. The population of RFE-response cases is a small subset of total approvals, and the speed likely reflects a batch of older RFE-response cases whose files were ready for a final decision at the same time, not a structural change in how USCIS handles RFE responses. The data brief does not tell us the exact mechanism; a single week is too thin to confirm any explanation.
