Form N-400 is used to apply for U.S. citizenship. If you are a Green Cardholder, you will have to file the application to apply for U.S. citizenship. However, all Green Card holders may not be eligible for U.S. citizenship, as they will have to wait for five years and satisfy the eligibility requirements for naturalization.
You can check your eligibility for U.S. citizenship using our basic eligibility quiz. It is mandatory to avoid common mistakes while completing Form N-400 and you must carefully prepare your paperwork. To understand the difference between this form and others, such as N400 vs N600, it’s crucial to know which applies to your situation.
The USCIS Form N-400, Application for Naturalization, consists of 18 parts and it is mandatory to complete all those parts. Leaving important parts of the application blank may result in the denial of your application. Hence you must see that you fill out the form completely, without mistakes.
