USCIS Changes Filing Location for Notices of Motion or Appeal Related to Citizenship Applications
U.S. Citizenship and Immigration Services (USCIS) announced that starting on January 1, 2016, those filing a Form I-290B, Notice of Motion or Appeal, in response to a decision on a Form N-600 (Application for Certificate of Citizenship) or N-600K (Application for Citizenship and Issuance of Certificate Under Section 322) must mail the I-290B to the Chicago Lockbox. USCIS will no longer accept these forms at local field offices.
USCIS will provide a 30-day grace period from January 1-30, 2016, for those who file an I-290B with the local office. Local field offices that receive a Form I-290B during this time will forward it to the Chicago Lockbox. After January 30, 2016, local field offices will return all I-290Bs for Forms N-600 or N-600K they receive and advise applicants to file instead at the Chicago Lockbox.
For those filing via the U.S. Postal Service, the address is:
P.O. Box 805887
Chicago, IL 60680-4120
For those filing via USPS express mail/courier, the address is:
