Master your N-400 interview in English or Vietnamese: 128 civics questions, mock interviews, and a Knowledge library on U.S. history & government.
Quốc Tịch USA is a free, bilingual (English/Vietnamese) study companion for the U.S. citizenship interview — built around the official USCIS N-400 civics test, with nothing to guess about what's actually on the exam.
WHAT'S INCLUDED
• All 128 official 2025 civics questions and answers, straight from the USCIS M-1778 study guide — plus the 2008 test set for applicants who filed before December 2020.
• Four ways to study: Learn (flashcards), Drill (spaced repetition), Mock Interview (timed, pass/fail like the real thing), and Listen (hands-free audio playlist for studying on the go).
• Studio-recorded, natural-sounding audio for every question and answer — not robotic text-to-speech.
• Speak your answer out loud and get instant feedback (English).
• Look up your own U.S. Senators, Representative, and Governor by state, with photos and current term info.
• A reader for official USCIS news and policy updates.
• Guides for N-400, I-130, I-129F, I-485, and I-765 — what each form is for, who's eligible, and what to expect.
• Daily study reminders you control — how many per day and what time window.
• Light and dark mode, and a clean, distraction-free design.
LEARN ABOUT AMERICA, NOT JUST THE TEST
Beyond the exam itself, a Knowledge library turns the civics test's subject matter into browsable, bite-size cards: every U.S. President, the 13 Colonies, all 50 States, and the founding documents and symbols behind American government. It's general U.S. civic knowledge worth having whether or not it's asked verbatim on your interview.
BUILT FOR REAL INTERVIEW DAY
Track your interview date, practice with realistic mock interviews scored the same way USCIS grades the actual test, and review exactly what you missed.
ENGLISH & VIETNAMESE, WITH MORE ON THE WAY
Every question, answer, and guide is available in both languages today, so you can study however's most comfortable and switch anytime. We're evaluating additional languages for future updates.
