Citizenship (N-400)
152 citizenship applications decided in Apr–Jun 2026 — sharply slower than a year earlier (−60%). 920 pending at quarter end (+6% vs a year ago). Approval rate 80.3%.
Backlog at the current pace: 18 months. That is how long the 920 pending would take to clear if decisions stayed at this quarter's rate and nothing new arrived (a year ago: 6.8 months). It is a measure of how far behind the office is, not a prediction for any one case.

USCIS field offices in Maine: questions
How many citizenship applications are pending in Maine?
920 N-400 applications were pending at USCIS field offices in Maine at the end of Apr–Jun 2026. Those offices decided 152 in the quarter (−60% vs a year ago).
Which USCIS field office do I go to in Maine?
Your field office is set by your home ZIP code. Your interview notice names it, and the official USCIS office locator (uscis.gov/about-us/find-a-uscis-office/field-offices) shows the office for any ZIP code.
Why are USCIS field offices slower now?
Field offices have been deciding far fewer applications in 2026 than a year earlier, while new filings keep arriving, so pending cases are piling up, and approval rates have fallen too. USCIS does not publish a reason for each office; its quarterly data shows the slowdown at almost every office at once, which points to agency-wide causes rather than anything about one office.
