Who can file Form N-400? Naturalization eligibility explained
Form N-400 is for lawful permanent residents who are eligible to naturalize, not for people who are already U.S. citizens through birth or parents. The key questions are which eligibility track applies, whether continuous residence and physical presence are intact, and whether any criminal or background issues create risk.
How do you become a U.S. citizen? Birth, parents, and naturalization explained
U.S. citizenship usually comes through one of three paths: birth in the United States, citizenship through U.S. citizen parents, or naturalization after becoming a lawful permanent resident. The details matter, especially for children born abroad and for green card holders preparing Form N-400.
What happens after you file Form N-400? Interview, test, oath, and citizenship rights
After you file Form N-400, USCIS usually moves your case through biometrics handling, a naturalization interview, English and civics testing unless an exception applies, and then an oath ceremony if approved. The exact process and timing depend on the field office, the filing date, and whether you qualify for age- or disability-based exceptions.
