N-400 Final-Stage Waits Rose 26 Days in One Week, Trend Points to 92 Days by Mid-October

The N-400 final-stage median (the wait from a case's last reported status to approval) rose from 46 days to 72 days in a single week, a 26-day increase that represents a +55.4% move week over week. An outlier flag fired at z=2.24 against the prior 4-week trailing mean, marking the reading as statistically unusual relative to the recent run. For context, the 12-week trailing average stands at 47 days, so this week's number sits 25 days above what had been a largely stable baseline through midsummer. The data does not tell us why this particular week produced such a large move; field office interview-scheduling waves and oath ceremony batching can shift the weekly median considerably, but a single week's sample of 687 approvals is not enough to confirm any mechanism.

This week's reading does not arrive in isolation. The 8-week regression slope is +5.1 days per week with an R² of 0.77, a well-fitted upward trend that began building in late July. The 12-week range ran from 31 days (the week of Aug 3) to 72 days this week, with most of the climb concentrated in the last six weeks. Compared with the same week last year, when the median was 83 days across 5,601 approvals, current waits remain lower. The 3-year same-week average also stands at 83 days. In that longer frame, N-400 final-stage waits are still running below historical norms, even after this week's move.

The trailing 12-week average is 47 days, meaning this week's 72-day reading sits 25 days above the period's central tendency. For applicants in the final stage of their N-400 adjudication (the phase between interview completion and oath ceremony scheduling), that gap is material. A case that would have cleared near the 47-day baseline a month ago now faces a considerably longer wait if the current pace persists into October.

The stage-duration data (drawn from the last 30 days across all pending N-400 cases) shows where the pipeline is holding volume. The processing stage, meaning USCIS is reviewing the case before scheduling an interview, carries a median of 113 days across 190,791 active cases, the largest single group at 24.4% of the total. This is the adjudication (USCIS's case-decision step, where approval, denial, or a request for more information is issued) queue proper: cases at this stage are waiting for an interview to be scheduled, not for a final decision. Interview Was Scheduled accounts for another 22.7% of cases (177,876 active), with a median of 53 days. The three oath ceremony stages combined hold roughly 21% of the pipeline, with medians ranging from 19 days (Oath Ceremony Notice Was Mailed) to 29 days (Oath Ceremony Will Be Scheduled).

Two smaller sub-populations show notably long medians. Cases at Interview Cancelled carry a median of 121 days (25th percentile, p25, of 74 days; 75th percentile, p75, of 164 days) across 22,332 cases, accounting for 2.9% of the active pipeline. These cases require rescheduling before they can reach adjudication, and they tend to age considerably in the process. The Oath Ceremony Cancelled group is smaller, at 7,104 cases and 0.9% share, but carries a median of 96 days. The data shows the duration at each status; it does not tell us the reason for the cancellations.
