Backlog at the current pace: 42 months. That is how long the 17,385 pending would take to clear if decisions stayed at this quarter's rate and nothing new arrived (a year ago: 5.4 months). It is a measure of how far behind the office is, not a prediction for any one case.

Questions about the USCIS Boston field office

How long does citizenship (N-400) take at the USCIS Boston field office?

USCIS does not publish one exact wait for each office. In Apr–Jun 2026, the Boston office decided 1,241 citizenship applications and had 17,385 pending at the end of the quarter. That is fewer decisions than a year earlier (−80%). At that pace, clearing everything pending would take about 42 months, compared with 5.4 months a year ago. Use the USCIS "Check Case Processing Times" tool for your form and office. It gives the time it takes to finish 80% of cases. The numbers on this page show whether your office is speeding up or slowing down, which that tool does not.

What is the N-400 approval rate at USCIS Boston?

USCIS approved 92.1% of the citizenship applications it decided at Boston in Apr–Jun 2026. The rate for all field offices was 81.8%.

How many green card applications are pending at USCIS Boston?

18,594 I-485 applications were pending at the Boston field office at the end of Apr–Jun 2026. It decided 1,554 in the quarter, with an approval rate of 93.5%. Employment-based cases are mostly decided at service centers, so most of these are family-based or humanitarian.

Why is the Boston field office slower?

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.

How do I know which USCIS field office handles my case?

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.
