Finding
Between the May 22 and June 23, 2026 USCIS publications, the published upper bound was higher for 255 of 492 comparable form-office-subtype series (51.8%), lower for 78 (15.9%), and unchanged for 159. Each series is equally weighted; the result is not weighted by application or receipt volume and does not measure how many applicants waited longer or establish a national backlog trend.
After excluding I-485, N-400, N-600, and N-600K — the four high-row-count field-office forms — the published upper bound was higher for 64 of 125 comparable series (51.2%), lower for 18 (14.4%), and unchanged for 43.
What this does and does not say
- The metric is the published upper bound of each USCIS processing-time range, compared per exact form-office-subtype series.
- Each series is equally weighted. The result is not weighted by application or receipt volume, so it does not measure how many applicants experienced a change.
- It does not say that most applicants, cases, forms, or offices waited longer, that processing times rose 51.8%, that a national backlog changed, that any policy caused the movement, or what July will show.
- Null upper bounds (no published time) are excluded before comparison; inverted raw endpoints are normalized before classification.
Methodology & reproducibility
Exact key: (form_name, office_code, form_subtype) — a series is comparable only when the same key appears in both publications with a non-null upper bound.
Unit normalization: each endpoint converted from its own unit to months before comparison, using 365.25 / 12 = 30.44 days per month; weeks × 7 ÷ DPM, days ÷ DPM, years × 12.
Inversion handling: if a normalized lower exceeds its upper, the two are swapped before classification.
Null treatment: series with a null upper bound in either publication are excluded.
Weighting: equal per exact-key series; no application- or receipt-volume weighting.
Primary result: 492 comparable series — 255 higher, 159 unchanged, 78 lower.
Sensitivity: excluding I-485, N-400, N-600, N-600K — 125 comparable series — 64 higher, 43 unchanged, 18 lower.
