Why Use a Fillable PDF for Your N-400?

Instead of downloading the PDF and opening it in a separate editor, simply click the Fill out this form button on this page. The Formize PDF Filler app loads in your browser, giving you a clean, interactive workspace.
Follow the step‑by‑step guide below to finish your application online.

Where to Submit Your Completed Form
