I-485 Final-Stage Wait Hits 12-Week High as Active Backlog Doubles

This week's median final-stage wait for I-485 applications climbed to 62 days, up 7 days from last week's 55 and the highest reading in the current 12-week window. The final-stage wait measures the time from a case's last recorded status update to its approval, a narrower clock than the full filing-to-approval timeline. The jump was enough to cross a statistical threshold: the outlier_week_high flag fired at a z-score of 2.06, meaning this week's reading sits about two standard deviations above the 8-week trend line, based on 8,912 cases approved.

The 12-week series traces a sharp recovery and a subsequent climb. The median fell from 59 days in early May to 30 days in W21 (week of May 18), then rose in each of the nine subsequent weeks, adding 32 days over that span. Against last year's comparable reading of 70 days (from a much smaller sample of 349 cases), the current 62-day median represents a 0% year-over-year delta. The 62-day reading is still below last year's comparable figure, but the direction of travel over the past nine weeks is upward at a slope of +2.2 days per week.

The total active I-485 caseload reached 251,541 cases as of July 27, up 125,382 cases (+99.4%) from May 7. The April 2026 filing-month group was the largest single contributor, adding 45,954 active cases over the period. The transmission mechanism is direct: when more cases enter the queue each week than are cleared, the median wait for future approvals tends to rise. The backlog growth over these 81 days is the structural context behind the weekly median's upward climb.

Clearance rates for recent filing-month groups (what the data calls cohorts, meaning all cases filed in the same calendar month) show how early in the queue most applicants remain. The March 2026 group, now 21 weeks old, has seen only 12.7% of its 73,808 total cases approved. The February 2026 group, at 25 weeks, is at 19.8% cleared across 59,464 total cases. At those paces, most cases filed in the first quarter of 2026 still have months of wait ahead. The April group, at 16 weeks old, is just 6.5% cleared across 81,239 total cases.

The uneven_centers anomaly flag fired this week with a spread value of 314.84 days between the fastest and slowest centers. The California Service Center (WAC) processed only 21 cases this week at a median of 539 days, while the Texas Service Center (SRC, handling 133 cases) sat at 50 days. WAC's small sample makes its median volatile; its reported 8-week slope of +61.5 days per week is not a reliable trend signal given that case count. The centers' case mix differs across all locations, so these comparisons reflect routing and volume as much as processing pace.

IOE accounted for 8,272 of this week's 8,912 approved cases (93%), with a median final-stage wait of 53 days. Its 8-week slope of +3.4 days per week at R²=0.96 means the upward trend there is consistent and statistically tight, with very little week-to-week scatter around the trend line. Because IOE handles nearly all of the approved volume, its trajectory is the primary driver of the overall form median. The National Benefits Center (MSC) handled 356 cases this week at a median of 227 days; its slope of +6.6 days per week sounds steeper, but an R² of 0.09 means there is little linear structure in the MSC series, and the direction cannot be asserted with confidence.
