Most citizenship test guides were written before October 2025 — before USCIS expanded the civics test from 100 questions to 128, doubled the number asked per interview, and raised the passing bar. This guide was built after that change, specifically to cover both versions clearly and completely.

Which test you take depends entirely on when you filed Form N-400, not when your interview happens to be scheduled. Fifteen chapters walk through the full shared content both tests draw from — American Government, American History, and Integrated Civics — followed by a dedicated chapter addressing exactly what's new and updated in the expanded 128-question version, so you're not left guessing which parts of an older guide still apply to you.

Beyond the civics content itself, the guide covers the naturalization process end to end: the English test's speaking, reading, and writing components, and what to actually expect walking into your interview.

Five hundred practice questions are organized into ten full-length tests — dedicated reviews of each question pool, a focused test on the 2025-specific additions, a comprehensive mixed review, and a full-length simulated interview — each with complete answer rationales. Fifteen original diagrams support the material throughout, including a simple chart showing exactly which test version applies to your situation.

Built for anyone preparing for their naturalization interview under either test version.
