N-400 Citizenship Interview Guide 2026: What to Expect

Quick Answer: What Happens at an N-400 Citizenship Interview?

During your N-400 citizenship interview, a USCIS officer reviews your Form N-400 and asks questions to confirm your identity, background, and eligibility for naturalization. You may also take the English and civics tests unless you qualify for an exception.

The officer may ask about information in your application, including your residence, travel, family history, employment, and other eligibility-related matters. If anything has changed since you filed, be prepared to explain the update and provide supporting documents when needed.

After the interview and required testing, USCIS will tell you the interview result or explain the next steps.

N-400 Citizenship Interview Process: Step by Step

The naturalization interview generally follows a series of steps. The exact questions and time needed can vary depending on your application, immigration history, and whether USCIS needs additional information.

1. Check in and confirm your identity. Bring your interview notice and the identification requested by USCIS.
2. Take an oath to tell the truth. The USCIS officer places you under oath before asking questions.
3. Review your Form N-400. The officer asks about your application and naturalization eligibility.
4. Complete the English and civics tests, if required. The requirements depend on your circumstances and which civics test applies to you.
5. Receive your results or next steps. USCIS may recommend approval, continue the case, request more information, or deny the application.

How Will You Know When Your N-400 Interview Is Scheduled?

USCIS will send you an interview appointment notice after your Form N-400 reaches the interview stage. The notice tells you when and where to appear. Review it carefully and follow the instructions provided for your appointment.

Can You Check Your Citizenship Interview Date Online?

Yes, USCIS online tools may help you track when your case moves to the interview stage. You can use USCIS Case Status Online with your receipt number to check for case updates. If you have a USCIS online account, notices or additional case information may also be available there.

However, do not rely only on an online status message. USCIS mails an interview appointment notice that provides the official date, time, and location of your naturalization interview. Follow the information on that notice when preparing for your appointment.

What If You Need to Reschedule the Interview?

If you cannot attend your scheduled interview, follow the rescheduling instructions on your appointment notice and contact USCIS as soon as possible. USCIS advises applicants to make every effort to attend the original interview because rescheduling can delay the naturalization process.

Do not simply miss the appointment. If you fail to appear and do not properly notify USCIS of the reason, USCIS may administratively close your Form N-400. A rescheduling request does not guarantee that USCIS will approve the request or provide a particular new interview date.

What Documents Should You Bring to Your N-400 Interview?

Bring the documents listed on your USCIS interview appointment notice and the identification and travel records USCIS requires for the naturalization interview. You may also need additional documents depending on your Form N-400 answers and individual circumstances.

Documents Most Applicants Should Bring

USCIS generally instructs naturalization applicants to bring:

• Your interview appointment notice
• Your Permanent Resident Card (Green Card), or Form I-551
• A state-issued identification document, such as a driver’s license
• All valid and expired passports and travel documents that show trips outside the United States since you became a lawful permanent resident

Review your appointment notice before the interview because USCIS may list other documents you need to bring. If USCIS has sent you a separate request for evidence or other notice, follow those instructions as well.

Additional Documents You May Need

Your additional documents depend on your naturalization basis, immigration history, and the answers on your Form N-400. If applicable, you may need evidence such as:

• marriage, divorce, or death certificates;
• documents supporting naturalization based on marriage to a U.S. citizen;
• tax returns, transcripts, or other tax records;
• certified court or arrest records;
• Selective Service registration documentation;
• evidence related to long trips outside the United States or continuous residence;
• Form N-648, Medical Certification for Disability Exceptions, if applicable; or
• documents specifically requested by USCIS.

You do not need every document on this list simply because you have an N-400 interview. Bring the records that apply to your case and anything USCIS specifically requests. For a broader filing and interview checklist, see our N-400 Documents Checklist.

How to Prepare for Your N-400 Interview

Prepare for your N-400 interview by reviewing the application you filed, checking for any changes, organizing your documents, and studying for the naturalization test if required. You should understand the information on your Form N-400, but you do not need to memorize your answers word for word.

1. Review the Form N-400 you submitted. Read through your application before the interview so you are familiar with the information you provided, including your addresses, employment, travel, family information, and background.
2. Identify anything that has changed since filing. Make note of changes to your address, job, marital status, trips outside the United States, legal history, or other answers on your application. Be prepared to explain these updates honestly during the interview.
3. Organize your interview documents. Gather the identification, travel records, and any case-specific documents that apply to you. Also review your appointment notice for anything USCIS specifically asks you to bring.
4. Prepare for the English and civics tests, if required. Review how the naturalization test works in our U.S. Citizenship Test Guide. You can also study the applicable official question bank in our Citizenship Test Questions and Answers guide.
5. Review your appointment details. Confirm the interview date, time, and USCIS field office listed on your notice. Plan your travel in advance and follow any arrival or security instructions provided by USCIS.

What Questions Does USCIS Ask at the N-400 Interview?

The USCIS officer generally asks questions from and about your Form N-400 and may ask follow-up questions to determine whether you meet the requirements for naturalization. The exact questions depend on your application, immigration history, and individual circumstances.

The officer may ask about:

• your name, date of birth, and other biographical information;
• current and previous addresses;
• employment history;
• trips outside the United States;
• marital and family history, when relevant;
• tax history or tax-related issues, when applicable;
• arrests, citations, charges, or other legal history, if applicable;
• answers related to your naturalization eligibility; and
• your attachment to the U.S. Constitution and willingness to take the Oath of Allegiance.

USCIS may ask additional questions if an answer needs clarification or if information has changed since you filed Form N-400. There is no single set of follow-up questions that applies to every applicant.

For more examples of the types of questions applicants may encounter, see our dedicated citizenship interview questions guide.

What Happens During the Naturalization Interview?

During the naturalization interview, a USCIS officer verifies your identity, reviews your Form N-400 and eligibility, and administers the English and civics tests if they apply to you. Your interview may vary depending on your application and individual circumstances.

Check-In, Identification, and Oath

When you arrive at the USCIS field office, follow the check-in and security instructions provided for your appointment. Bring your interview appointment notice and the identification USCIS requires.

When your interview begins, the USCIS officer will verify your identity and place you under oath. You must answer the officer’s questions truthfully. Follow any additional instructions on your appointment notice because procedures can vary by location.

USCIS Reviews Your Form N-400

A major part of the interview is the officer’s review of your Form N-400. The officer may confirm information you provided, ask follow-up questions about your background, and review evidence related to your eligibility for naturalization.

You should also be prepared to discuss changes since you filed. For example, your address, employment, marital status, travel history, or other information may have changed. Updating or correcting information during the interview is different from intentionally providing false information.

If an issue involves a complicated immigration, criminal, or legal matter, the officer may ask for additional information or evidence before USCIS makes a decision.

English Test

Unless you qualify for an exception, the naturalization test includes speaking, reading, and writing English. Your speaking ability is evaluated through your responses during the Form N-400 interview.

For the reading test, you must correctly read 1 of up to 3 sentences. For the writing test, you must correctly write 1 of up to 3 sentences. Certain applicants are exempt from some English requirements.

See our U.S. Citizenship Test Guide for the full English test requirements and exceptions.

Which Civics Test Will You Take at Your N-400 Interview?

The civics test you take depends on when you filed Form N-400. USCIS currently uses two test versions for applicants whose naturalization cases are still pending.

For details about how the tests work, see our U.S. Citizenship Test Guide. To study the official question banks, use our Citizenship Test Questions and Answers guide.

How Long Does the N-400 Citizenship Interview Take?

There is no single USCIS-published time limit or standard duration for every N-400 citizenship interview. The amount of time needed depends on the applicant and the issues USCIS needs to review.

Your interview may take more or less time depending on your Form N-400, changes or corrections since filing, eligibility questions, English and civics testing, and whether the officer needs to review additional documents.

The length of the interview is different from the overall N-400 processing time. If you want to know how long USCIS may take to process a naturalization application from filing through a decision, see our N-400 Processing Time guide.

Can Someone Come With You to the Naturalization Interview?

Most applicants attend and answer the USCIS officer’s questions themselves. However, an eligible applicant may use an interpreter, attend with an attorney or accredited representative, or request a disability accommodation depending on the circumstances.

Interpreter

If you qualify to take the civics test in a language other than English, you may need to bring an interpreter who is fluent in both English and the language you use for the interview.

When an applicant provides an interpreter for an eligible USCIS interview, Form G-1256, Declaration for Interpreted USCIS Interview, may be required. The interpreter must be able to interpret accurately, be competent, and remain impartial and unbiased. USCIS decides whether the proposed interpreter meets its requirements.

Not every naturalization applicant is eligible to use an interpreter.

Attorney or Accredited Representative

You may be represented at your naturalization interview by an attorney or a Department of Justice-accredited representative. Legal representation is optional and is not required for every N-400 interview.

An attorney or accredited representative appearing on your behalf generally uses Form G-28, Notice of Entry of Appearance as Attorney or Accredited Representative, to establish representation with USCIS.

Disability Accommodation or Support Person

If you have a disability that affects your ability to participate in the interview, you can request a reasonable accommodation from USCIS. The type of accommodation depends on your needs and may involve changes to how the appointment is conducted or other assistance that allows you to participate.

USCIS provides an online process for requesting disability accommodations for appointments. An accommodation request must generally be submitted for each appointment where it is needed.

A disability accommodation is different from Form N-648, which is used to request a medical exception from the English and/or civics requirements. See our Form N-648 Guide for details about that exception.

What Happens After the Citizenship Interview?

After your N-400 interview and any required testing, USCIS will provide information about your results and what happens next. USCIS may grant the application, continue the case because more information or testing is needed, or deny Form N-400.

You Receive Your Interview Results

After the interview, USCIS generally gives you Form N-652, Naturalization Interview Results, with information about the outcome of your interview and naturalization tests.

This does not always mean you will receive a final decision on Form N-400 that day. USCIS may need additional time or information before deciding the application.

If USCIS Recommends Your Application for Approval

If USCIS determines that you meet the naturalization requirements, your application may be recommended for approval or approved. The next step is the Oath of Allegiance.

Some applicants may be able to attend an oath ceremony on the same day when one is available. Otherwise, USCIS will send a notice with the ceremony details.

Passing the interview does not by itself make you a U.S. citizen. You become a U.S. citizen only after taking the Oath of Allegiance at a naturalization ceremony.

If USCIS Needs More Information

USCIS may continue your Form N-400 instead of making a final decision if it needs additional information or evidence.

If USCIS asks you to provide documents or other information, follow the instructions and deadline in the notice you receive. What USCIS requests depends on the issue that needs to be resolved.

A continued case does not always mean USCIS has issued a standard Request for Evidence. Follow the specific notice USCIS provides.

What If You Fail Part of the English or Civics Test?

If you do not pass the English test, civics test, or both at your first interview, USCIS generally gives you a second opportunity to take the part you failed.

USCIS normally schedules the retest 60 to 90 days after the first interview. You are retested only on the portion of the naturalization test that you did not pass; you do not automatically repeat the entire N-400 interview or every part of the test.

See our U.S. Citizenship Test Guide for more information about test results and retesting.

If USCIS Denies Form N-400

If USCIS denies your naturalization application, it will provide a written notice explaining the reason for the decision. The options available after a denial depend on the reason and the instructions in the decision notice.

For a detailed explanation of possible next steps, including when a hearing may be available, see our N-400 Denial Guide.
