What is the purpose of Form N-400, Application for Naturalization?


Form N-400, Application for Naturalization, is used to apply for U.S. citizenship through a process known as naturalization. Naturalization, one of four basic ways to become a U.S. citizen, is a process that lets people born outside of the United States become U.S. citizens.
