N-400 Citizenship Interview: What to Bring and What to Expect

The N-400 naturalization interview is the final in-person hurdle before becoming a U.S. citizen. Unlike the I-485 interview — which focuses largely on your immigration history and eligibility — the N-400 interview also includes two official tests: an English language test and a U.S. civics test. Being well-prepared for all three components makes the process smoother and significantly reduces anxiety.

You can check where your case stands using GreenLight's Status Decoder. When your interview has been scheduled, your status will show "Interview Was Scheduled" — see the Interview Was Scheduled status guide.

What Happens at the N-400 Interview

The N-400 interview has three main components:

1. English language test: USCIS officers assess your English ability throughout the interview — not through a formal separate test, but by observing your ability to read, write, and speak English during the appointment. The officer will ask you to read one or two sentences aloud from an official USCIS list and write one sentence from dictation. The threshold is basic functional literacy, not fluency.
2. Civics test: The officer asks up to 20 questions drawn from the official list of 100 civics questions. You must answer at least 6 correctly to pass. If you fail on the first attempt, you are given a second chance at a second interview scheduled within 60–90 days. If you fail the second time, your N-400 will be denied — though you may refile.
3. Eligibility review: The officer reviews your N-400 application, asks you to confirm your answers under oath, and asks additional questions about your background, travel history, moral character, and any yes/no eligibility questions on the form.

Documents to Bring to Your N-400 Interview

• Interview appointment notice (Form I-797C) — required for entry.
• Permanent Resident Card (green card) — current and all expired green cards.
• Valid passport — all passports you have held, including expired ones.
• U.S. tax returns — typically 5 years, matching the continuous residence period.
• Any court records — if you have any arrests, citations, or court appearances (even if expunged), bring certified court dispositions for all of them.
• Travel records — if you have traveled outside the U.S. during the 5-year (or 3-year for qualifying spouses of citizens) continuous residence period, bring documentation of your trips.
• Marriage documents — marriage certificate, divorce decrees for all prior marriages, death certificates if a prior spouse is deceased.
• Proof of name change — if you want your naturalization certificate issued in a new name, bring the court order for the name change.
• Any selective service documentation — if you are a male who lived in the U.S. between ages 18–26, bring proof of selective service registration or an explanation of exemption.

Bring originals and a full copy set of everything. The officer may retain copies.

The 100 Civics Questions

USCIS publishes the complete list of 100 civics questions and answers on uscis.gov. The officer will ask up to 20 questions verbally; you must answer at least 6 correctly to pass.

The questions cover American history, government structure, geography, and rights and responsibilities. Examples: "What is the supreme law of the land?" (The Constitution), "Who makes federal laws?" (Congress), "What are the two major political parties in the United States?"

Modified civics test for seniors: Applicants who are 65 years or older and have been a permanent resident for at least 20 years may take a modified, shorter civics test — only 20 questions are on their study list, and 6 of 10 must be answered correctly. These questions are marked with an asterisk (*) on the official USCIS list.

Interview Tips

• Arrive 15 minutes early. Bring only what you need — field offices have security screening.
• Speak slowly and clearly. If you do not understand a question, it is fine to ask the officer to repeat or rephrase it.
• Answer questions truthfully. Any misrepresentation — even about something you think is minor — is a serious problem for naturalization eligibility.
• If you have a complex legal history (criminal record, prior immigration violations), consult an immigration attorney before the interview.

What Happens After the N-400 Interview

• Approved same day: Some field offices conduct oath ceremonies the same day as the interview, particularly if a large group oath is scheduled.
• Approved, oath scheduled separately: Most commonly, you receive a written approval and are scheduled for a separate oath ceremony within 2–6 weeks at the field office or a local courthouse. You cannot travel on a U.S. passport or vote until after the oath.
• Continued: The officer needs more time or additional documentation. You will receive written instructions on what to provide.
• Denied: You will receive a written decision with reasoning. You have the right to request a hearing with a USCIS officer within 30 days, or to appeal to a federal district court. Consult an immigration attorney promptly.
