Works offline. No account. No subscription.

Naturalizing through Form N-400? The civics test is the part most applicants worry about. This app turns all 128 official questions into bite-size practice you will actually remember, so you walk into your USCIS interview calm and ready.

ALL 128 OFFICIAL QUESTIONS
Every question from the official USCIS civics test, organized into American Government, American History, and Symbols and Holidays. Search, bookmark, filter by rating, and study one topic at a time. Questions are shown in the exact wording USCIS officers use.

EVERY ACCEPTED ANSWER
Civics answers are flexible — more than one phrasing can be correct. Each card reveals the full list of accepted answers, so you can learn to say it your own way and still be marked right.

LOCATION-BASED ANSWERS
Questions about your US senator, representative, governor, or state capital depend on where you live. Save your own answers once and see them every time you review — no more memorizing someone else's state.

MOCK INTERVIEWS
The real test is oral: a USCIS officer asks questions out loud and you need enough correct answers to pass. Practice with realistic mock interviews, self-mark your spoken answers, and review what you missed.

SPECIAL PREP FOR 65+ APPLICANTS
Applicants aged 65 or older with 20+ years as a permanent resident can study a reduced set of 20 starred questions and may test in their native language. Filter the bank to focus on exactly those questions.
