I-539 Wait Times Rose 27 Days in One Week, Driven by a 247-Day Center Gap
The week of June 8 brought the highest I-539 final-stage median in 12 weeks, with an anomaly detector firing at z = 2.95 against the prior 8-week trend. The divergence between California and Texas service centers now accounts for most of the aggregate reading.
The I-539 final-stage wait reached 168 days the week of June 8, up 27 days from 141 days the prior week and the highest reading in the 12-week window. The move is not random noise: an outlier flag fired at z = 2.95 against the prior 8-week trend line, and the center spread between WAC (California Service Center, at 301 days) and SRC (Texas Service Center, at 54 days) widened to 247 days, triggering the uneven-centers flag. The 8-week slope of +7.8 days per week points to deterioration that has been building since mid-April, not a one-week artifact. With roughly 40,844 active cases in the pipeline as of June 19, up 44% in 43 days, the forward pressure on wait times appears likely to persist.
- The I-539 final-stage median rose 27 days in a single week to 168 days, the largest single-week move in the 12-week window and a z = 2.95 outlier against the prior 8-week trend.
- WAC (California Service Center) processed 656 approved cases this week at a median of 301 days, while SRC (Texas Service Center) processed 944 cases at 54 days, a 247-day gap that triggered the uneven-centers flag at 186.76.
- The 8-week slope of +7.8 days per week (R² = 0.62) means the median has added roughly 62 days since mid-April; if the trend continues, the model projects a range of ~175 to 224 days by the week of July 6.
- The total active I-539 pipeline grew 44% in 43 days (roughly 28,361 to 40,844 active cases from May 7 to June 19), with the May 2026 filing-month group alone accounting for 9,244 currently active cases.
- Cases that received and responded to an RFE (Request for Evidence) cleared in a median of 18 days, roughly one-sixth the 109-day median for plain-processing cases, consistent with the rfe_fast anomaly flag this week.
168 days: the spike that ended a quiet spring
The week of June 8 produced the sharpest single-week move in the 12-week series: a 27-day rise from 141 days to 168 days, a 19.1% jump. As recently as the week of April 6 (W15), the median sat at 66 days. The anomaly detector flagged this week as an outlier at z = 2.95, meaning the reading sits nearly 3 standard deviations above the 8-week trend line computed against the prior trailing window, not a long-term baseline. The sample of 2,097 approved cases is solid and does not on its own explain the move.
A trend that has been building since April
The pattern carrying this week's reading is classified as accelerating_fast: a slope of +7.8 days per week over the last 8 weeks, meaning the median (the 50th percentile, where half of approved cases finished faster and half slower) has added roughly 62 days since mid-April. The 12-week trailing average sits at 103 days, placing this week's 168-day reading 65 days above recent norms. The R² of 0.62 on the 8-week regression is directionally credible but not tight enough to treat any exact future number as a precision estimate.
The broader pipeline context aligns with that pressure. Total active I-539 cases rose from roughly 28,361 to 40,844 in just 43 days (May 7 to June 19), a 44% increase. The May 2026 filing-month group accounts for 9,244 of those currently active cases, the largest single-month contributor to the active backlog of pending cases. A growing queue facing the same adjudication (USCIS's decision step) capacity is consistent with upward pressure on final-stage wait times, though the data does not identify the precise mechanism.
Two centers, 247 days apart
The clearest explanation for this week's aggregate reading is the divergence between service centers. WAC (the California Service Center, USCIS's Laguna Niguel facility) approved 656 cases this week at a median of 301 days. SRC (the Texas Service Center) approved 944 cases at a median of 54 days. EAC (Vermont Service Center) sits at 221 days across 350 approved cases this week. The uneven_centers flag fired at 186.76, well above the 12-day threshold that defines unusual imbalance. The case mix differs across centers, so the comparison is structural rather than a pure performance ranking, but the scale of the gap is large enough that routing alone may account for much of the aggregate movement. WAC's slope of +13.6 days per week with R² = 0.54 is the most aggressive trajectory among active centers this week.
