The document provides an overview of revisions made to the Form N-400 Application for Naturalization. Key changes include improved instructions, a new user-friendly format, clarified eligibility requirements, additional questions on national security and moral character, and the addition of preparer, applicant and interpreter statements. The form now also utilizes 2D barcode technology to facilitate more accurate data intake. The naturalization eligibility criteria and filing fees remain unchanged. The revised form is available on the USCIS website and will be mandatory to use after a 90 day transition period.
