  • The Complete Guide to Applying for U.S. Citizenship (Form N-400)

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).
  • Pass a U.S. history and government (civics) test.

Documents Required for Form N-400

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

  • A copy of your Permanent Resident Card (Green Card).
  • Marriage certificate (if applying through marriage to a U.S. citizen).
  • Tax returns or IRS transcripts.
  • Proof of travel outside the U.S. (if applicable).
  • Court records (if you have any legal history).

Submitting a complete and organized package helps avoid delays or requests for additional evidence (RFEs) from USCIS.
