Is the N-400 available online?

Yes, Form N-400 is available online on the USCIS website at uscis.gov/n-400. The form is provided as a free downloadable PDF, and most applicants can also complete and submit it electronically through a free USCIS online account at my.uscis.gov.

The PDF version is available for download, printing, and submission by mail to a USCIS Lockbox; the online version permits the applicant to fill out the form interactively, save progress, upload supporting documents, pay the filing fee electronically, and submit the entire application without ever printing or mailing anything. The online filing pathway has expanded steadily since USCIS first introduced it for N-400 in 2017, and it is now available to nearly all naturalization applicants who file from inside the United States, including spouses of U.S. citizens, military service members and their spouses, and applicants requesting language exceptions or disability waivers. A small number of categories (for example, applicants seeking certain humanitarian exceptions or with very unusual circumstances) may still need to file by paper.

Online filing has several advantages: USCIS reports that online cases are processed faster than paper cases on average (often by 30 to 60 days), the online interface flags missing information before submission, and applicants can track case status, receive notices, and respond to USCIS requests for evidence directly through their account. Online filers pay $710 (April 2024 fee schedule), compared with $760 for paper filers. The online form supports uploading supporting documents (passport copies, marriage certificates, tax transcripts, and other evidence) directly to the USCIS file, eliminating the need to mail documents.

Applicants who prefer paper filing can still download the PDF, complete it by hand or with Adobe Acrobat, and mail it with supporting documents to the appropriate USCIS Lockbox address (which depends on the applicant's state of residence and is listed in the form instructions). Both pathways result in the same legal document and the same adjudication; the choice is logistical, not substantive.
