I-751 Backlog Grew 18% in 18 Days While Cohort Approvals Sit Near Zero
The week of May 18, 2026 produced a 45-day median for I-751 final-stage approvals, but only 278 cases cleared. Behind that number, the active pending backlog reached 61,949 cases, up 9,631 in 18 days, and six recent filing-month groups have combined for fewer than 25 total approvals.
The I-751 weekly median dropped to 45 days for the week of May 18, its lowest point in the 12-week window. That figure covers 278 approved cases out of an active pending backlog of 61,949 cases, which grew by 9,631 (+18.4%) in just 18 days. The two numbers measure entirely different things: the median captures cases that happened to clear this week; the backlog captures cases still waiting, many for years. Six filing-month groups spanning January through May 2026 have a combined approval count of roughly 25 cases out of more than 62,000 filed. The falling median is a real but narrow data point. The accumulation trend is the broader signal.
- The I-751 active backlog reached 61,949 cases, growing by 9,631 cases (+18.4%) in just 18 days between May 7 and May 25, 2026.
- The January 2026 filing-month group (11,740 cases, now 20 weeks old) had accumulated 5 total approvals as of this week's snapshot, a 0.0% clearance rate.
- Cases at the 'Case Is Still Being Processed By USCIS' stage show a 301-day median wait across 34,359 cases, the stage where the largest share of the backlog is concentrated.
- RFE (Request for Evidence) response cases cleared in a 23-day median this week versus 100 days for plain-processing cases, a 4.4x speed ratio that appears to reflect queue routing rather than a structural advantage.
- The 4-week forecast carries a residual standard deviation of 44 days and an R² of 0.27, producing a range of ~22 to 111 days by the week of June 22 rather than a reliable single number.
45 days, 61,949 cases: two numbers that don't agree
The I-751 final-stage median came in at 45 days for the week of May 18, the lowest reading in 12 weeks. But that figure rests on 278 approved cases, a small slice of the queue. At the same time, the active backlog (pending cases not yet adjudicated) stood at 61,949 cases as of May 25, up 9,631 cases (+18.4%) from 18 days earlier. These measure different things: the weekly median tells you how long cases that cleared this particular week had been waiting at their last status; the backlog count tells you how many cases are still in line.
When the median drops but the backlog grows
The divergence appears to follow a pattern in which USCIS is approving a narrow set of cases quickly while intake continues to outpace overall adjudication (USCIS's decision step) volume. The monthly status counts for April 2026 show 9,524 cases entering processing status that month against only 9 approvals. In April 2025, by contrast, the same monthly count showed 2,110 approvals. The throughput decline from roughly 2,110 approvals per month to single digits may reflect resource reallocation, interview scheduling shifts, or intake volume growth; the data brief does not identify a single cause.
A volatile trend with no reliable direction
The 12-week median series for I-751 final-stage wait runs from 45 days to 185 days, with no consistent directional pattern. The 8-week regression slope is -10.2 days per week, but the R² of 0.27 falls well below the 0.4 threshold that would support a confident trend claim. In plain terms, the downward slope is as likely to reflect week-to-week noise as any sustained improvement. This week's 25th percentile (p25) sits at 27 days and the 75th percentile (p75) at 173 days, a spread of 146 days that reflects the wide variation in how long cases wait before final action.
The 278-case sample this week sits above the 200-case reliability floor but at the lower end of the 12-week range, which ran from 141 cases (W19) to 528 cases (W18). When fewer cases are approved in a week, the median reflects a narrower and potentially less representative slice of the queue. The W18 reading (528 cases, 69-day median) and W17 (498 cases, 51-day median) show that even larger-sample weeks produce widely varying medians, reinforcing the noisy character of the series.
RFE cases clearing faster than plain ones: what that means
Cases that had received and responded to an RFE (Request for Evidence, USCIS's standard follow-up letter asking for missing documents) cleared in a 23-day median this week. Cases without an RFE took a 100-day median. That is a 4.4x speed ratio, with the RFE-response group clearing faster. One possible explanation is that RFE-response cases get placed in a distinct review queue after the response arrives and a subset of those cases cleared together this week; another is a batch effect from cases with responses filed in the same period. The data brief does not identify the mechanism.
4.44x RFE response cases clear faster than the plain processing cohort.
Receiving an RFE is not a denial signal. Most cases that receive an RFE are ultimately approved, and the faster median for RFE-response cases this week reflects queue routing and week-specific dynamics rather than any general advantage to having received one. Applicants with pending RFE responses should not read this week's number as predictive of their own timeline.
This week's faster median for RFE-response cases reflects queue routing, not that an RFE puts a case on a faster track in general.
