CitizenPrep helps you pass the U.S. naturalization civics test —
with practice exams, flashcards, an AI mock interview, and answers that stay
current with elections.
Which test should I study? Applicants who filed
Form N-400 on or after Oct 20, 2025 take the 2025 test (128 questions);
before that, the 2008 test (100 questions). Pick yours in Settings.
Why do some answers say "Live"? Answers that change with
elections (President, your senators, governor, and more) update
automatically so you never study outdated officials.
How do I see my representative? Enter your ZIP code in
Settings. It's used only to look up your U.S. Representative and never
leaves your device.
What does CitizenPrep Pro do? Everything you need to pass
is free. Pro is a one-time purchase that removes ads.
Restoring a purchase: Settings → Restore Purchases.
