Preamble: US Citizenship Test

Eight questions on the civics test have no answer. Not a hard answer — no answer. USCIS prints "Answers will vary" or points at its own updates page, because the answer depends on where you live or on who holds office the day you are interviewed. That is one question in sixteen. On a 20-question interview, you will probably be asked one of them. Preamble is built around that. WHICH TEST DO YOU TAKE? USCIS switched to the 2025 civics test — 128 questions, 20 asked, 12 correct to pass — for anyone who filed Form N-400 on or after 20 October 2025. Filed before that date? You take the 2008 test: 100 questions, 10 asked, 6 to pass. It is decided by your filing date, not by preference. Preamble asks for your date and tells you which applies. Both lists are included in full. THE EIGHT WITH NO ANSWER Your senators. Your representative. Your governor. Your state capital. The President, the Vice President, the Speaker of the House and the Chief Justice. Other apps either print "Visit uscis.gov" as though that were the answer, or bundle a list of names that goes out of date at the next election. Preamble ships no officeholder names at all. It links you to the authority for each one, records what you found and the date you confirmed it, warns you when an answer is getting old, and drills you on your own answer alongside the rest. Your state capital is filled in for you, because that is the one that never changes. EVERY ANSWER USCIS ACCEPTS Ask "What is the form of government of the United States?" and USCIS accepts Republic, Constitution-based federal republic, or Representative democracy. Some questions have twenty-four acceptable answers. An app that shows you one teaches you that your own correct answer was wrong. Preamble shows all of them, word for word from the USCIS list. An automated check proves on every release that all 918 question strings appear verbatim in the government document they came from. THE TEST IS SPOKEN, SO THE PRACTICE IS TOO No multiple-choice buttons. A real interview is an officer asking and you answering out loud, and picking one of three options is far easier than recalling the answer cold. Preamble shows the question, waits while you say it aloud, reveals every accepted answer, and asks you to mark yourself. THE MOCK INTERVIEW STOPS WHEN THE REAL ONE WOULD The officer does not ask all 20. USCIS stops the moment you reach 12 correct — or 9 wrong, so real interviews are shorter than people expect. ALSO INCLUDED • The 65/20 special consideration: the 20 starred questions, 10 asked, 6 to pass • The English test: all 64 reading words and 75 writing words USCIS publishes NOTHING LEAVES YOUR IPHONE No account, no analytics, no advertising, no trackers. The app makes no network requests of its own and works in airplane mode. Your answers live in one file on your device, and deleting the app deletes them. The privacy label says Data Not Collected because that is literally true. FREE, AND WHAT COSTS MONEY All 128 questions and every accepted answer are free, permanently — and so is recording your own answers to the eight that have none. You should be able to open the USCIS PDF next to this app and check every word before spending anything. Full Prep is $14.99 once: unlimited practice, unlimited mock interviews, and the record of what you still get wrong. It is not a subscription. Nothing auto-renews. There are no ads at any tier.
