Understanding Form N-400: What You Need to Know
Form N-400, officially called the “Application for Naturalization,” is your key to beginning the journey toward becoming a U.S. citizen. If you are a green card holder meeting specific eligibility criteria, this form is the first step in officially applying for naturalization through the U.S. Citizenship and Immigration Services (USCIS). See our guide on “U.S. Citizenship Eligibility” to learn the full requirements, exceptions, and steps you must meet before applying for naturalization.
Completing the N-400 accurately is essential, because it collects all the details USCIS needs to decide if you meet every requirement for citizenship. Mistakes or missing information can cause delays, uncertainty, or even setbacks—so giving it your careful attention is crucial.
When you file Form N-400, you’ll need to provide information about:
- Your personal details and immigration background
- Your residency and employment history
- Trips taken outside the United States
- Your family members
- Your moral character and legal history
After you submit the form, USCIS will schedule you for biometrics (fingerprinting), and later, a naturalization interview, civics test and oath ceremony.
It’s important to use the most recent version of the form and carefully follow instructions. You can file online or by mail, and must attach necessary documents and fees. Done right, filing Form N-400 is the first real step in embracing your future as a U.S. citizen—and enjoying all the benefits that citizenship brings.
Every detail you provide brings you closer to the oath ceremony, where your journey becomes official. Filing correctly and without delay means fewer setbacks, faster approval, and peace of mind for you and your family. The sooner you file correctly, the sooner you can take the oath and proudly call yourself a U.S. citizen.
Before starting your naturalization journey, it’s essential to confirm that you meet the eligibility requirements for U.S. citizenship.
