As part of the naturalization process, all U.S. citizenship applicants are required to provide supporting documents to U.S. Citizenship and Immigration Services (USCIS). Which documents are necessary depends on each applicant’s situation. Green card holders applying for naturalization based on their marriage to a U.S. citizen, for instance, must provide additional documentation, such as a marriage certificate and their spouse’s U.S. passport.
Applicants submit the supporting documents at different stages of the naturalization process. In the tables below, you’ll see which documents are required to be submitted with your Application for Naturalization (Form N-400) and which documents you must bring to your naturalization interview. Make sure to also check out our guide to creating digital documents the way the U.S. government prefers.
For the flat rate of $395, Boundless helps you complete your entire naturalization application, including all supporting documents, independent attorney review, and support from the moment your application is filed until you obtain U.S. citizenship. If you’re not sure whether you qualify for citizenship, you can check your eligibility through Boundless without providing any personal information.
