CitizenPrep: US Citizenship

Pass the US citizenship civics test with confidence — with the only study app built to NEVER go stale.
ALWAYS-CURRENT ANSWERS
Who's the President? The Speaker? Your senators, governor, representative? Other apps bake these in and go out of date after every election. CitizenPrep updates them automatically — within minutes of a change, no app update needed. What you study is what's true today.
AI MOCK INTERVIEW — LIKE THE REAL THING
A virtual USCIS officer interviews you by voice, hands-free. He asks aloud, you answer out loud, he tells you if you got it — and moves on, just like the real oral test. He grades like a real officer: lenient on wording, strict on substance, and stops early the moment you pass. You can type instead anytime.
BOTH OFFICIAL TESTS
• 2025 test (128 questions, 20 asked, 12 to pass) — N-400 filed on/after Oct 20, 2025
• 2008 test (100 questions, 10 asked, 6 to pass) — filed before that
• 65/20 mode: 65+ and a permanent resident 20+ years? Study just your 20 marked questions.
YOUR STATE, YOUR ANSWERS
Pick your state for your real senators, governor, and capital. Enter your ZIP (optional) to see YOUR U.S. Representative — looked up on your device.
STUDY YOUR WAY
• Practice exams scored exactly like the real test
• Flashcards for every question
• "Learn more" — a clear AI explanation of any answer, in your language, read aloud
• Progress tracking and a readiness score
• English and Spanish (the test itself is in English, as at USCIS)
HONEST AND FREE
Everything you need to pass is free: every question, practice exams, flashcards, and the AI interview. No sign-up. One optional purchase — CitizenPrep Pro — simply removes ads.
