How to apply for citizenship

Applying for citizenship can be very confusing. If possible, we recommend you have a lawyer help you. It can be expensive, but you may be able to find free and low-cost legal help online and in your community.

1. Complete the N-400 (Application for Naturalization)

The first step is to complete the Application for Naturalization. This is a government form called the N-400. You can send the completed form in the mail or you can apply online. Download the N-400 form or apply online.

Important: from December 2019, the U.S. Citizenship and Immigration Services, USCIS, is only accepting the 2019 form. Make sure any form you are filling out has this at the bottom of each page: Form N-400 Edition 09/17/19. If it has a different date, download a new form and start again.

You have to include many papers with the application and you also have to pay the fee. Here is a checklist of what you need to include when you submit your N-400 application. You have to include two passport photos with your application. Remember to write your “A-number” on the back of these photos. Some people can apply for a fee waiver so you do not have to pay the fee.

If you are filling out your paperwork without a lawyer, the free website CitizenshipWorks.org will help you through the application steps. Citizenshipworks can also connect you to free legal help online or to a Citizenshipworks partner in your area if you need extra help.

Applying for citizenship usually costs $725. You may be able to get a fee waiver if you can prove your income is low enough. A waiver means that you will not have to pay. Find more details about how to apply for a waiver.

Important: Make a copy of your N-400 before you send it.

2. Save your receipt and check your application online after you apply for citizenship

You will receive a letter of receipt that says USCIS received your application. Keep this and write down the 13-digit receipt number. Take a photo of the receipt on your phone and email it to yourself to make sure you don’t lose it. You can use the receipt number to check the status of your application.

3. Complete your biometric screening

Biometric screening is a security check. You will be asked to go to an office on a certain day and time. Make sure to go to this appointment and to arrive on time! At the appointment, they will take your fingerprints. This means they will stamp your fingerprints and run the picture through a system to make sure you are not a criminal. Learn more about the biometrics appointment.

4. Attend your citizenship interview

Complete an interview with an officer from the USCIS. Learn more about the naturalization interview and how to prepare for the test.

5. Take the civics test

During your interview, you will take a test about US civics, history, and government. On this exam, you must answer 6 out of 10 questions correctly. You can take our citizenship practice quiz to see if you are ready for the test. If you are not ready, you can join our free citizenship class to prepare you for the exam.

6. Wait for a decision

You will receive a written decision from USCIS about your application. You might receive your decision on the day of your interview or you might receive it later in the mail. The decision will say if your application was:

  • Granted (this means you passed!)
  • Continued (this means USCIS is doing more research about you or it means you might have failed the English or Civics exams. You can take them again.)
  • Denied (this means USCIS decided you are not eligible for naturalization. If this happens, you may request an appeal)

7. Attend your citizenship ceremony

If you did pass, you will be ready to complete your citizenship ceremony and take the Oath of Allegiance. This is when you pledge loyalty to the United States.

If you have questions about the process, there are organizations you can call. These organizations offer advice in some newcomer languages. Find free or low-cost citizenship help near you.
