Application for Naturalization

Naturalization is the process through which an immigrant can become a United States citizen. To apply for naturalization, you must:

be at least 18 years of age at the time you apply;
have been a lawful permanent resident for the past three or five years (depending on which naturalization category you are applying under);
have continuous residence and physical presence in the United States;
be able to read, write, and speak basic English;
demonstrate good moral character;
demonstrate knowledge and understanding of U.S. history and government.

Form N-400, Application for Naturalization, can be filed with USCIS by mail or online. The application must be supported by the required documents, including your birth certificate, a copy of your most recently issued passport, a copy of your green card, and your tax returns for the past five years.

After you apply, you will receive a receipt notice from USCIS. You will be able to use the receipt number to keep track of your case status on the USCIS portal. For more information, see our blog on how to track USCIS case status.

You can also apply for citizenship online through USCIS designated portal. We provide online filing services and will happily answer your questions about it.

The next step after filing the application will be a biometrics appointment at the USCIS office closest to your home. Make sure to follow the instructions on the appointment notice.

If USCIS does not require additional evidence (in which case they will send you a request detailing the needed additional information), you will get an interview notice. The notice will include the time and place of the interview and a list of documents you will need to bring to the meeting.

If the interviewing officer finds you eligible for Naturalization, USCIS will notify you about the time and date for your Oath Ceremony. After taking the oath, you will receive your Certificate of Naturalization.
