U.S. Citizenship Test: 100 vs. 128 Questions

Quick answer (verified 2026-07-06 by CivicFlare):

Your test version depends on when you filed (or plan to file) your Form N-400. Before October 20, 2025 → the 100-question 2008 version. On or after October 20, 2025 → the 128-question 2025/2026 version.

One of the most common questions applicants ask is: "Do I take the 100 or the 128 question citizenship test?" The answer depends entirely on the date you file (or filed) your Form N-400, Application for Naturalization — not on your interview date.
