U.S. Citizenship and Immigration Services (USCIS) has changed the filing locations for Form I-130, Petition for Alien Relative. Domestic Petitioners will mail their stand-alone I-130 applications to either the Chicago Lockbox or the Phoenix Lockbox, depending on where they reside in the United States. The new filing locations will be updated with the corresponding addresses on Jan. 1 on the Form I-130 Direct Filing Locations page. This effort will balance workloads between the two locations and provide more efficient and effective processing of Form I-130.
