What to Expect at Your N-400 Citizenship Interview

US Citizenship Test Editorial Team13 min read

Last updated: March 15, 2026

The N-400 citizenship interview is the final major step before becoming a US citizen. During this appointment, a USCIS officer reviews your application under oath, tests your English ability, and administers the civics test — all in a single session that typically lasts 15 to 30 minutes.

Understanding what happens at each stage removes the uncertainty and helps you walk in prepared. This guide covers everything from what to bring, to how the interview unfolds step by step, to the three possible outcomes you may receive at the end.

How Long Does the Citizenship Interview Take

Most N-400 interviews last between 15 and 30 minutes, though some appointments may run longer if the officer needs to review complex travel history or request 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.

Typical time breakdown for each stage of the citizenship interview
Interview StageApproximate Time
Check-in and waiting15–45 minutes
Oath to tell the truth1–2 minutes
N-400 application review5–15 minutes
English reading test2–3 minutes
English writing test2–3 minutes
Civics test5–10 minutes
Officer's decision2–5 minutes

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 (10 questions, need 6 correct). If you filed on or after October 20, 2025, you take the 2025 test (20 questions, need 12 correct). 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 state-issued photo ID — A driver's license, state ID, or passport.
  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. Travel records — Passport pages showing all international travel since becoming a permanent resident.
  7. Evidence of selective service registration — Required for male applicants who registered or were required to register (ages 18–26).

Step-by-Step Interview Walkthrough

The citizenship interview follows a consistent structure at every USCIS office. Knowing each step in advance helps you stay calm and focused throughout the process.

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.

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. Spelling and grammar do not need to be perfect — the officer evaluates whether you can write in English at a basic level. 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: 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: 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 with 20 or more years of permanent residency, 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.

The officer stops asking questions once you reach the passing score. For example, on the 2008 test, if you answer the first 6 questions correctly, the officer will not ask the remaining 4.

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. However, 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:

Q1.What is your current home address?

Answer: Provide your full street address, city, state, and ZIP code exactly as listed on your N-400 or updated if you have moved.

Q2.Have you taken any trips outside the United States since you became a permanent resident?

Answer: List each trip with the country visited, departure date, and return date. The officer may ask follow-up questions about longer trips.

Q3.Have you ever been arrested, cited, or detained by any law enforcement officer for any reason?

Answer: Answer honestly. If yes, provide details and bring any relevant court documents. Even minor incidents must be disclosed.

Three Possible Interview Outcomes

At the end of your interview, the USCIS officer stamps Form N-652 to indicate the result. There are three possible outcomes:

The three possible outcomes of your N-400 citizenship interview
OutcomeWhat It MeansWhat Happens Next
Approved (Granted)You passed all portions of the interview. Your application is approved for naturalization.You may take the Oath of Allegiance the same day (if available) or receive a notice scheduling your oath ceremony. Once you take the oath, you are a US citizen.
Continued (N-14)The officer needs additional evidence or documentation to make a decision, or you failed the English or civics test and need a re-examination.USCIS sends you Form N-14 listing the required documents or scheduling a re-exam. You must respond within the timeframe specified. Your case remains open.
DeniedYou did not meet the eligibility requirements for naturalization. Common reasons include failing the English or civics test twice, continuous residence issues, or moral character concerns.USCIS sends Form N-20 explaining the denial. You have 30 days to request a hearing (Form N-336) to appeal the decision. You may also reapply with a new N-400.

Most applicants who prepare thoroughly receive an approval. According to USCIS data, the overall naturalization approval rate is above 90%. Preparation for the civics test makes the biggest difference — visit our frequently asked questions page for more details on pass rates and study strategies.

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 is designed to be straightforward, not adversarial. Officers want to help you succeed.

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 extremely difficult to replace if lost. Consider making copies and storing them separately from the original.


The N-400 interview may feel intimidating, but it follows a clear, predictable structure. By understanding each step, bringing the right documents, and preparing for both the English and civics tests, you can walk into your interview with confidence.
