What can I do if USCIS denies my naturalization application?
If you think that USCIS was wrong to deny your naturalization application, you may request a hearing with an immigration officer. Your denial letter will explain how to request a hearing and will include the form you need. The form for filing an appeal is the "Request for Hearing on a Decision in Naturalization Proceedings under Section 336 of the INA" (Form N-336). You must file the form, including the correct fee, to USCIS within 30 days after you receive a denial letter.If, after an appeal hearing with USCIS, you still believe you have been wrongly denied naturalization, you may file a petition for a new review of your application in U.S. District Court.
