Practice test

The real 2025 test reads you up to 20 questions and stops as soon as you have 12 right; this mock gives you all 20.

This last unit is a mock test. The first quiz has 20 questions drawn from every section of the 2025 list, the same number as the real standard form. Score it the way the officer does: you pass at 12 correct. On the real test the officer would stop at 12 correct or 9 wrong, but here you can answer all 20 and read the explanations. The second quiz has 10 of the 20 starred questions, the format for 65/20 applicants, who need 6 correct. If you take the 2008 test, use the flashcards in each unit marked 2008 version; its standard form is 10 questions with 6 to pass.

The quiz gives you choices to tap, but the interview has none. The officer reads the question and you answer in your own words. So before tapping, say your answer out loud, then check it against the choices. The speaking drill below works the same way: play a line, pause, answer it aloud, and compare with the answer printed in the line.

Each explanation gives the question number on the official 2025 list, so a missed question points straight back to its unit: 1 to 15 Principles, 16 to 35 Congress, 36 to 62 the President, courts and states, 63 to 72 Rights, 73 to 89 the colonial period, 90 to 99 the 1800s, 100 to 118 recent history, 119 and 120 geography, and 121 to 128 symbols and holidays.

What happens at the interview

The interview takes place at a USCIS office. The officer places you under oath, goes through your Form N-400 with you, and gives the English and civics tests during the same appointment. If you pass and your application is approved, you are scheduled to take the Oath of Allegiance at a naturalization ceremony, and you become a citizen when you take the oath. If you fail a part, you are retested on that part only at a second interview, usually 60 to 90 days later.

Last checks before the interview

A week before your interview, look up the answers that change: the President, the Vice President, the Speaker of the House and the Chief Justice on uscis.gov/citizenship/testupdates, plus your own senators, representative and governor. Confirm which version you take from the filing date on your receipt notice. Then run this mock test until you reach 12 or more correct several times in a row, and spend extra time on the questions you missed; this site keeps them in your review list.

The Oath of Allegiance

The text below is the oath new citizens take, as set out in federal regulations (8 CFR 337.1). It is not part of the test, but question 67 asks about its promises, and reading it once makes those answers easier to remember.

I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty, of whom or which I have heretofore been a subject or citizen; that I will support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I will bear arms on behalf of the United States when required by the law; that I will perform noncombatant service in the Armed Forces of the United States when required by the law; that I will perform work of national importance under civilian direction when required by the law; and that I take this obligation freely, without any mental reservation or purpose of evasion; so help me God.
