On April 1, 2024, USCIS issued a new naturalization form (Form N-400) for public use. To assist practitioners and volunteers in completing the new N-400 form, ILRC developed this annotated form. The annotated form explains many of the questions, why specific questions are on the form, how to complete certain questions, and which questions are “red flags” and thus need advice from experienced attorneys or Department of Justice accredited representatives. This annotated form will help guide practitioners and volunteers while completing the new N-400. Please note that this annotated form is not a substitute for knowing the full details of all the legal requirements for naturalization and the risks of applying for naturalization if the applicant falls into any of the “red flag” categories.
