N-400 Processing Time and Steps: US Citizenship Application Guide

Applying for US citizenship is the last step of a long journey, and the N-400 is the form that gets you there. The question on everyone’s mind is simple: how long will it take? This guide gives you the current timeline, the steps from filing to the oath, the fees, and the delays worth avoiding, all in plain English.

How long does the N-400 take right now?

Form N-400 is the Application for Naturalization, the form a permanent resident files to become a US citizen. If you are still weighing whether to take that step, our comparison of permanent resident vs citizen sets out exactly what changes. As of July 2026, most applications take about 6 to 14 months from filing to the oath ceremony, though some field offices run longer. Your local office workload is the single biggest factor, so two people who file the same week in different cities can finish months apart. These are planning estimates, not promises. Check the USCIS processing times page for your office. Our USCIS processing time checker shows the same figure in one step.

The N-400 process, step by step

1. File Form N-400. You submit the application online or by paper, with your documents and fee. USCIS sends a receipt notice with your receipt number.
2. Biometrics. You attend a short appointment for fingerprints and a photo, used for background checks.
3. Interview. A USCIS officer reviews your application and asks about your background. This is also where the tests happen.
4. English and civics tests. You take an English test, covering speaking, reading, and writing, and a civics test on US history and government.
5. Decision. The officer approves, continues, or denies the case. A continuation usually means more evidence or a retest is needed.
6. Oath ceremony. If approved, you attend an oath ceremony, take the Oath of Allegiance, and become a US citizen. You receive your Certificate of Naturalization that day.

N-400 fees in 2026

Filing online is cheaper and easier to track. Some applicants qualify for a reduced fee or a fee waiver, and certain military applicants pay nothing. If you want a fee waiver or reduced fee, you must file on paper. Who qualifies for each, and what to attach, is set out in our guide to the cost of US citizenship. A rejected filing does not refund the fee, so check everything before you submit.

Am I eligible to naturalize?

Most applicants must meet these general requirements. Your own situation can change what applies, so treat this as a starting point, not a ruling on your case.

• Be a green card holder for at least 5 years, or 3 years if married to and living with a US citizen
• Be at least 18 years old at the time of filing
• Show continuous residence and physical presence in the United States
• Show good moral character
• Be able to pass the English and civics tests, unless you qualify for an exemption
• Be willing to take the Oath of Allegiance

The interview and the citizenship test

The interview is where most people feel nervous, but it is manageable with preparation. The officer confirms the answers on your application, then gives the English test, which checks that you can speak, read, and write basic English, and the civics test, a set of questions on US history and government. USCIS publishes the official study materials, so you can practice exactly what will be asked. If you do not pass a portion, you usually get a second chance within a set period.

Common N-400 delays and how to avoid them

• Errors or gaps on the application, especially in the travel and address history
• Missing documents at the interview, such as proof of a name change or tax records
• Not preparing for the tests, which can lead to a continuation
• Trips outside the US that break the continuous residence requirement
• Unresolved issues in your background that need extra evidence

Most of these are avoidable with an accurate application and good preparation before the interview.

The verdict

Naturalization is the most rewarding step in the immigration journey, and it is largely within your control. File a complete and accurate N-400, prepare for the English and civics tests using the official materials, and keep your documents organized for the interview. Do that, and the timeline is mostly a matter of your field office. Rush or cut corners, and a continuation can add months you did not need to lose.
