Becoming a U.S. citizen is a proud and life-changing achievement. It grants you the right to vote, access to additional benefits, and the ability to fully participate in civic life. The process begins with Form N-400, Application for Naturalization, which is submitted to the U.S. Citizenship and Immigration Services (USCIS).
At In N Out Immigration, we understand that navigating immigration paperwork can be complex. Our professionals are dedicated to assisting applicants in completing and filing Form N-400 accurately and efficiently.
Who Is Eligible to Apply for U.S. Citizenship?
To qualify for naturalization, applicants generally must meet the following requirements:
- Be at least 18 years old.
- Have held lawful permanent resident (Green Card) status for at least 5 years, or 3 years if married to a U.S. citizen.
- Demonstrate continuous residence and physical presence in the United States.
- Possess good moral character.
- Be able to read, write, and speak basic English (some exceptions apply).

Documents Required for Form N-400
When preparing your N-400 application, ensure that you include all required supporting documents. Common documents include:

- Marriage certificate (if applying through marriage to a U.S. citizen).
