N-400 interview questions and how to answer them

Most of what a USCIS officer asks at your citizenship interview comes from one document: the Form N-400 you already filed. After you are put under oath, the officer goes through your answers, asks follow-up questions, and fixes anything that has changed. That conversation is also your English speaking test.

That means nobody can give you your exact questions ahead of time, because they depend on what you wrote. You can still learn which parts of the form the officer works through and where the follow-up questions tend to come from. Everything below uses the current edition of the form, dated 01/20/25.

What the officer has to cover

The USCIS Policy Manual says the officer's questions must cover every requirement for naturalization and generally focus on your application, the documents you sent, and anything the background investigation turned up. The officer may ask any question that bears on your eligibility.

The topics it lists:

• Biographical information, including marital history and military service
• When you became a permanent resident and how long you have been one
• Trips outside the United States since then
• Where you have lived and worked
• English and civics
• Moral character and any criminal history
• Loyalty to the United States and the principles of the Constitution
• Memberships in certain organizations
• Your willingness to take the Oath of Allegiance

Before the interview the officer also reviews your A-file, the record of your dealings with immigration agencies. An answer on your N-400 that does not match something in that file will come up.

Questions about you and your history

Parts 1 through 8 of the N-400 are the facts of your life: your eligibility basis, your name and personal details, where you have lived, your marriages, your children, your jobs and schools, and your time outside the country. Expect the officer to confirm these one at a time. Typical questions sound like:

• What is your current address, and how long have you lived there?
• Are you married? Have you been married before?
• How many children do you have?
• Where do you work now?
• Have you traveled outside the United States since you filed?

These are examples. The officer will word things their own way and ask more where your answers need it. Trips are a common example: for any trip that lasted more than 6 months but less than a year, USCIS asks for evidence that you kept your continuous residence in the United States.

The "have you ever" questions in Part 9

Part 9, "Additional Information About You," is the long list of yes-or-no questions most people mean when they talk about N-400 interview questions. On the current form it runs to 37 numbered items, many with lettered parts.

When a question includes the word "EVER," the form says it covers anything you did anywhere in the world at any time, unless the question says otherwise.

Items	What they ask about
1-2	Registering to vote or voting, and claiming to be a U.S. citizen
3-4	Overdue taxes, and calling yourself a "nonresident alien" on a tax return
5-14	Communist or totalitarian parties, violence, torture, armed groups, weapons, and child soldiers
15-16	Crimes and arrests, and whether you finished any sentence or probation
17	Prostitution, drugs, marriage fraud, polygamy, smuggling people, illegal gambling, child support, and public benefits
18-21	False information to the government, and removal or deportation
22	Selective Service registration
23-29	The draft and service in the U.S. armed forces
30	Hereditary titles
31-37	The Constitution and the Oath of Allegiance

The crimes section needs the most care. The form tells you to list every offense, including ones from before you turned 18, even if your record was sealed or expunged or someone told you it no longer counts. If you answered yes anywhere, expect follow-up questions on the details. USCIS's N-400 checklist names the records it expects for each kind of yes, such as arrest reports and court dispositions. Keep copies of what you sent.

Questions about the oath

Items 31 through 37 ask whether you support the Constitution, whether you understand the full Oath of Allegiance, whether you are willing to take it, and whether, if the law requires it, you are willing to bear arms, do noncombatant service in the armed forces, or do work of national importance under civilian direction.

Read the oath itself, printed in Part 16 of the form, before the interview, and make sure you know what words like "noncombatant" and "allegiance" mean. Your answers here are part of the speaking test too, so be ready to say what each question is asking in your own words.

When an answer has changed

Your N-400 answers are signed under penalty of perjury, and the officer treats them as part of the record. If something changed after you filed, say so: a new address, a new job, another trip, a marriage, a child, a ticket, an arrest. The officer records corrections made during the interview, and can also take a sworn statement on any point.

At the end of the review you sign Part 15, "Signature at Interview," in front of the officer. That signature swears that everything on the form, including the corrections made that day, is true.

How to get ready

Start with a copy of the N-400 you filed. Read every answer and write down what is different now.

Then practice out loud. Have someone read you the Part 9 questions in the officer's wording and answer each one with a short full sentence, such as "No, I have never claimed to be a U.S. citizen." You get used to the long wording and practice for the speaking test at the same time.

You may bring an attorney or an accredited representative to the interview. If a yes answer on your form worries you, talk to one before the appointment. This page is study help, not legal advice.

The same appointment includes the reading and writing tests and the civics test. For the whole sitting, see what happens at the naturalization interview, and for the civics questions, the 128 questions on the 2025 test or the 100 questions on the 2008 test.

Our app has a free step-by-step interview guide. Pro adds a full mock interview with a spoken officer, and its N-400 round reads out sample questions like "Have you ever claimed to be a U.S. citizen?" so you can practice answering out loud. Those questions are general practice rather than your own form, so pair them with your copy of the N-400.
