Please note: The Instructions to Form N-400 frequently refer to information in the USCIS document A Guide to Naturalization. We encourage you to review those referenced sections of the Guide as you complete this form.

This version of the N-400 Application for Naturalization is available below in two files - the form itself, and its instructions.

The first is the form; it is large (2.6 MB); we recommend that you download it directly to your local computer, rather than fill out the form through your web browser. In order for most users to do this (using a Windows PC), "right-click" on the link to the fillable form and select "Save Link As" (in Netscape) or "Save Target As" (in Internet Explorer). 

The second file is the instructions.
