Immigration: Citizenship/Naturalization (N-400)

For those looking to become a naturalized U.S. citizen, filing the Application for Naturalization (N-400) is the first step. This application can be filled out and submitted at your local U.S. Citizenship and Immigration Services (USCIS) office or online if you meet certain requirements. In this blog post, we will discuss what is required to complete the N-400 application, as well as what happens after you submit it.

The Application for Naturalization.

The N-400 (Application for Naturalization) is a form that requests personal information about you and your family. It asks questions such as:

• Have you lived in the U.S. continuously for the past five (5) years? (or three (3) if married to a U.S. citizen).

• How old were you when you first came to the U.S.?

• Do you have a criminal record?

The form also asks about your work history, education, and English language abilities. You will need to provide proof of your identity and eligibility for naturalization, such as your passport or birth certificate.

The Process.

Although you can submit the form on your own, having an experienced Immigration Attorney handling your case will decrease the chance of error and delay. The first step is to accurately fill out the application form and file it with USCIS. Then, the following steps will then occur:

1. You will receive a receipt notice in the mail that includes your Application Receipt Number (ARN). You should keep this number as it can be used to track your status.

2. Once USCIS receives and processes your application, they will send you a biometrics appointment notice to have your fingerprints taken at an Application Support Center (ASC). This usually happens within two weeks of submitting the form but may take months if there is a backlog.

3. After this, it's just a matter of waiting until USCIS schedules an interview with you. They will notify you by mail of the time, date, and location. You should bring your ARN number, passport, proof of U.S. residency, and marriage certificate (if applicable) to the interview.

How Long Does Naturalization Application Take For N-400?

From submitting the application to being sworn as a U.S. citizen, the entire process generally takes about six months. While the process can sometimes be much faster, it can take longer if there is a backlog at USCIS.

What Documents Are Needed For The N-400 Application?

You will need to provide proof of your identity and eligibility for naturalization—a photocopy of your permanent resident card (Front and Back). If you are married to a U.S. citizen, your spouse can help you fill out Form N-400 by providing information about themselves and their work history. Also, please have available your passport or birth certificate, and documents that show you've been living in the U.S., such as a driver's license, utility bills, or tax returns.

What Happens After I Submit My Application?

Once your application is processed, attend the interview, and pass your Civics test, you will be a U.S. citizen! USCIS will mail you your Certificate of Naturalization after approving your application. Congratulations!
