What to Expect at Your N-400 Citizenship Interview

The N-400 citizenship interview is the final major step before becoming a US citizen. In a single session that usually lasts about 20 to 30 minutes, a USCIS officer reviews your application under oath, tests your English ability, and administers the civics test.

Below is the sequence USCIS officers follow, the documents you must bring, and what each of the three possible outcomes (approved, continued, denied) means for your case.

How Long Does the Citizenship Interview Take?

Most N-400 interviews last about 20 to 30 minutes. Appointments that include the 20-question 2025 civics test can run longer, as can interviews where the officer reviews complex travel history or requests additional documents. Plan to spend one to two hours at the USCIS office total, including check-in and waiting time.

Arrive at least 30 minutes before your scheduled appointment. Late arrivals may have their interview rescheduled, which can delay the entire naturalization process by weeks or months.

The civics test portion varies depending on which test version applies to you. If you filed your N-400 before October 20, 2025, you take the 2008 test (up to 10 questions, 6 correct to pass). If you filed on or after October 20, 2025, you take the 2025 test (up to 20 questions, 12 correct to pass). Learn more about the differences between the 2008 and 2025 civics tests.

What to Bring to Your Interview

Bringing the correct documents is essential. Missing a required item could result in your interview being rescheduled or your case being continued. Here is what you need:

1. Appointment notice (Form I-797C) — The letter USCIS mailed you with the date, time, and location of your interview.
2. Permanent resident card (green card) — Your current, valid green card. Bring it even if it is expired.
3. Valid photo ID — A driver's license or state ID card.
4. Any documents listed on your appointment notice — USCIS may request specific items such as tax returns, travel records, court documents, or marriage certificates.
5. Your N-400 application copy — Not strictly required, but strongly recommended so you can review your answers before the interview.
6. All passports and travel documents — Current and expired passports covering your time as a permanent resident, showing all international travel.
7. Evidence of Selective Service registration — Required for male applicants who registered or were required to register. Registration is required from the 18th birthday until the 26th, so ages 18 through 25.

Step-by-Step Interview Walkthrough

The citizenship interview follows a consistent structure at every USCIS office. Here is each step in the order it happens.

Step 1: Check-In

When you arrive at the USCIS office, present your appointment notice and photo ID at the front desk. A staff member will check you in and direct you to a waiting area. You may wait anywhere from a few minutes to over an hour, so bring something to read or review while you wait.

Step 2: Oath to Tell the Truth

The USCIS officer calls your name and escorts you to a private interview room. Before anything else, the officer asks you to raise your right hand and swear or affirm that everything you say during the interview will be truthful. This oath is legally binding. Providing false information can result in denial and potential legal consequences.

Step 3: N-400 Application Review

The officer goes through your N-400 application question by question. You will be asked to confirm or correct information about your name, address, employment history, travel outside the United States, marital status, and moral character questions. The officer may ask follow-up questions about any answer that needs clarification.

This portion also serves as part of your English speaking test. The officer evaluates your ability to understand and respond to questions in English throughout the entire interview.

The questions here use legal terms that appear on no study list — affirm, cited, affiliated, renounce. Our plain-English guide to the N-400 interview vocabulary the officer uses explains each one.

Step 4: English Reading Test

The officer asks you to read one out of three sentences aloud in English. The sentences use vocabulary from American civics and history. You must read one sentence correctly to pass this portion. If you read the first sentence incorrectly, you get two more attempts with different sentences.

Step 5: English Writing Test

The officer dictates one out of three sentences for you to write down in English. You must write one sentence correctly to pass. Per the USCIS scoring guidelines, spelling, capitalization, and punctuation errors will not fail you as long as the sentence's meaning stays clear — but you must never abbreviate a dictated word. As with reading, you get up to three attempts.

Step 6: Civics Test

This is the portion most applicants spend the most time preparing for. The USCIS officer reads civics questions aloud, and you answer verbally. The test is oral; there is no written multiple-choice exam.

Which version you take depends on when you filed your N-400:

• 2008 civics test: up to 10 questions from a pool of 100. You need 6 correct answers (60%) to pass. Applies to applications filed before October 20, 2025.
• 2025 civics test: up to 20 questions from a pool of 128. You need 12 correct answers (60%) to pass. Applies to applications filed on or after October 20, 2025.

If you are age 65 or older and have lived in the US as a permanent resident for 20 or more years at the time you file your N-400, you qualify for the 65/20 special consideration. Under this exception, you are tested on 10 questions drawn from a designated list of 20, and you need 6 correct to pass. Read our full guide to the 65/20 citizenship test exception for seniors.

The officer stops asking questions once the result is decided. On the 2008 test, the test ends when you reach 6 correct answers: answer the first 6 correctly and the officer will not ask the remaining 4. On the 2025 test, the officer stops after 12 correct answers (pass) or 9 incorrect answers (fail), so you may hear as few as 12 of the 20 questions, per the Federal Register implementation notice for the 2025 civics test (Doc. 2025-18050).

You can practice citizenship test questions online to prepare for both the 2008 and 2025 versions of the civics test.

Step 7: Decision

After completing all portions of the interview, the officer informs you of the result. You receive one of three possible outcomes: approved, continued, or denied. The officer typically explains the decision and any next steps before you leave.

N-400 Application Review Questions

During the application review portion, the officer asks questions directly from your N-400. These are not trick questions. They are straightforward confirmations of the information you submitted, but you should be prepared to answer clearly and consistently.

Common topics the officer covers include:

• Your full legal name and any previous names
• Current home address and how long you have lived there
• Employment history for the past five years
• Travel outside the United States (dates, destinations, duration)
• Marital status and spouse information
• Number of children and their details
• Moral character questions (arrests, crimes, tax obligations)
• Willingness to take the Oath of Allegiance
• Understanding of your rights and responsibilities as a citizen

Here are examples of questions the officer may ask during the N-400 review:

Three Possible Interview Outcomes

At the end of your interview, the USCIS officer gives you Form N-652, Naturalization Interview Results, with the outcome checked. There are three possible outcomes:

Most applicants who prepare thoroughly receive an approval. USCIS has historically approved roughly 90% of naturalization applications, and about 9 in 10 applicants pass the test on the first attempt, per USCIS naturalization test performance data. Those figures reflect the 2008 test; USCIS has not yet published pass rates for the 2025 test. Preparation for the civics portion makes the biggest difference, and our frequently asked questions page covers pass rates and study strategies in more detail.

How to Prepare for Your Interview

Preparation is the single best way to reduce stress and increase your chances of passing on the first attempt. Follow these seven steps in the weeks before your interview:

1. Study the civics questions — Review all 100 questions (2008 test) or 128 questions (2025 test) from the official USCIS study materials. Use our free practice citizenship test questions online to quiz yourself under realistic conditions.

2. Practice your English reading and writing — Read and write sentences using civics vocabulary daily. USCIS publishes official reading and writing vocabulary lists on their study resources page.

3. Review your N-400 thoroughly — Go through every section of your application. Make sure you can recall all dates, addresses, employers, and travel history accurately.

4. Gather your documents early — Collect all required documents at least a week before your interview. Make copies of everything.

5. Practice speaking about your application — Have a friend or family member ask you N-400 review questions out loud. Practice answering clearly and concisely in English.

6. Know your interview location — Look up the USCIS office address and plan your route. Do a test drive or transit check if possible. Account for traffic and parking.

7. Get a good night's sleep — Arrive well-rested and calm. The interview follows a fixed script, and you can ask the officer to repeat or rephrase any question.

Common Mistakes at the Interview

Avoiding these frequent mistakes can make the difference between approval and continuation:

1. Arriving late or on the wrong day — Double-check your appointment notice for the correct date, time, and office location. Arriving late may force USCIS to reschedule your interview, delaying the process by months.

2. Forgetting required documents — Leaving your green card, photo ID, or appointment notice at home can result in a rescheduled or continued interview. Pack your documents the night before.

3. Providing inconsistent answers — If your verbal answers contradict what you wrote on your N-400, the officer may question your credibility. Review your application beforehand so your answers match.

4. Not disclosing travel or legal issues — Failing to mention trips outside the US or past arrests, even minor ones, can raise red flags. USCIS already has access to travel and criminal records, so honesty is essential.

5. Panicking during the English or civics test — If you do not understand a question, it is acceptable to ask the officer to repeat it. Take a breath before answering. Rushing leads to unnecessary mistakes.

6. Bringing unauthorized people into the interview room — Only you and a qualified interpreter (if applicable) or attorney may enter the interview room. Family members must wait outside.

What Happens After You Pass

Once the officer approves your application, you are one step away from becoming a US citizen. The final step is the Oath of Allegiance ceremony.

If a same-day ceremony is not available, USCIS mails you Form N-445 with the date and location of your scheduled oath ceremony, usually within two to six weeks after your interview.

At the oath ceremony, you:

1. Check in and return your green card to USCIS.
2. Take the Oath of Allegiance to the United States.
3. Receive your Certificate of Naturalization — the official document proving your US citizenship.

After the ceremony, you are a US citizen with full rights and responsibilities. You can:

• Apply for a US passport at your local post office or passport agency.
• Register to vote in federal, state, and local elections.
• Petition for family members to immigrate to the United States.
• Travel freely without the restrictions that apply to permanent residents.
• Run for most elected offices at the local, state, and federal level.

Keep your Certificate of Naturalization in a safe place. It is difficult and slow to replace if lost, so consider making copies and storing them separately from the original.
