What happens after I file Form N-400? Timeline and processing times

What are the steps after I file?

Here is the usual order after U.S. Citizenship and Immigration Services (USCIS) gets your Form N-400. Not every case includes every step.

1. You get a receipt notice

   It shows that USCIS accepted your form, and gives you a receipt number.

2. You go to a biometrics appointment, if needed

   USCIS takes your fingerprints, photo, or signature for identity and background checks.

3. USCIS reviews your case

   It may ask for more evidence during this time.

4. You go to your interview

   An officer reviews your application and gives you the English and civics tests, unless you qualify for an exemption.

5. USCIS makes a decision

   If you are approved, you still become a citizen only when you take the Oath of Allegiance.

What if USCIS rejects my form?

A rejection isn't a denial. It means USCIS didn't accept the form for processing. The instructions say that USCIS returns the application and any fees and tells you what's wrong, and that you can correct it and file again.

Your form isn't considered properly filed until USCIS accepts it. Common reasons include a missing signature, the wrong fee, or missing pages. Our guide on how to fill out Form N-400 lists more.

When do I get my receipt notice?

It depends on how you filed.

Keep your receipt notice somewhere safe. You use the number to track your case. As of November 2026, the notice also extends your green card for 2 years past its expiration date. Our documents checklist explains how that works.

What happens at the biometrics appointment?

If USCIS needs your biometrics, it sends a notice (Form I-797C) with the date, time, and location. The appointment is at an Application Support Center, and in general it covers your fingerprints, photo, and signature.

What to bring. USCIS says to bring your appointment notice, plus valid photo ID, such as your green card, passport, or driver's license. Your notice may list more. You don't need your attorney or representative there.

What you confirm. You sign that the information in your application was complete, true, and correct when you filed, under penalty of perjury. USCIS recommends reviewing your copy of the form first. If you can't confirm this in good faith, the instructions say you'll have to return for another appointment.

What to wear. USCIS may use this photo on your Certificate of Naturalization, so it recommends wearing clothing that's acceptable to show on your certificate.

Language help. If you don't understand spoken English, USCIS says you should bring someone who can translate for you.

To reschedule, you must show good cause. As of November 2026, you can do this through your online account until 12 hours before the appointment, unless it has already been rescheduled twice. Otherwise, call the USCIS Contact Center at 800-375-5283. Going to a different center than the one on your notice without rescheduling first won't work, USCIS says.

How long does the N-400 take, and how do I check my case?

USCIS has three self-service tools:

• Case status (uscis.gov/casestatus) needs only your receipt number. USCIS says it shows the same information a phone representative would give you.
• Processing times (uscis.gov/processingtimes) shows how long USCIS is taking on cases. For Form N-400, USCIS says to check your local field office, even if your notice lists the National Benefits Center.
• Your online account can send automatic case alerts, and lets you upload evidence and send secure messages. If you filed on paper, USCIS mails a letter about setting up an account.

Times vary and USCIS updates them monthly, so we don't list numbers here.

What the posted time means. As of November 2026, it's how long USCIS took to complete 80% of decided cases over the last six months. So it isn't a promise, and some cases take longer.

When you can ask about your case. USCIS allows questions only for certain cases. On the processing times page, enter the received date from your receipt notice. The tool then gives you either an estimated date when you can ask, or a link to submit a question.

What if USCIS asks for more evidence?

USCIS may send a Request for Evidence, or RFE, asking for documents it needs. It may also ask for originals of anything you sent as a copy. An RFE doesn't mean your application is being denied.

• Your deadline is on the notice. As of November 2026, the longest deadline USCIS can give is 12 weeks, and it says regulations don't allow more time.
• Send everything at once. USCIS says it generally doesn't wait for a second response if you send only part of what it asked for.
• Don't ignore it. If you don't respond by the date, USCIS may deny your application.

If you filed online, USCIS notifies you by text or email, and you respond through your account. Follow the instructions on your notice if you filed on paper.

What if I move while my case is pending?

You must tell USCIS. As of November 2026, you have 10 days after moving. USCIS encourages you to do it through your online account as soon as you move, and to enter the receipt number of each pending case.

If your move changes which office handles your case, you may get a new appointment notice from that office. Members of the armed forces who are transferred or deployed after filing can call the Military Help Line at 877-247-4645.

What if there's a mistake?

It depends on whose mistake it is.

• USCIS made a mistake on a notice or document. USCIS points people to its online tool at uscis.gov/e-request. You can also use it if a notice never arrived, or to ask for an accommodation at an appointment.
• You need to add something. While your case is pending, you can send evidence that USCIS didn't ask for through your online account.
• There's an error in your form. USCIS says you can't change an online application after you submit it. While your case is pending, you can send additional information through your account. At your interview, the officer goes over your answers with you under oath, and the record can include changes the officer makes based on what you say. Part 15 of the form, signed at your interview, covers your answers "including corrections". Tell your officer about anything that needs fixing.

If the mistake involves one of the sensitive questions in Part 9, talk to a legal professional first.

When will I get my interview?

USCIS schedules it once the earlier steps on your case are done, and sends you a notice with the date, time, and office. Filing online means you can also see the notice in your account. Bring the notice with you. Our guide to what to expect at the interview has more.

As of November 2026, USCIS says it has 120 days from your first interview to issue a decision. If it doesn't, you may be able to ask a federal district court to review your application.

What should I keep doing while I wait?

You need to keep meeting the requirements until you take the oath. That includes the residence rules and good moral character. You can also start preparing for the tests.

If anything changes while your case is pending, such as an arrest, a long trip, or a problem with your taxes, consider talking to a legal professional.
