On January 1, 2012, U.S. Citizenship and Immigration Services (USCIS) changed the filing locations for Form I-130, Petition for Alien Relative.

Domestic petitioners will now mail their stand-alone I-130 applications to either the Chicago Lockbox or the Phoenix Lockbox, depending on their residence in the United States.

There will be no change in filing locations when submitting Form I-130 along with Form I-485, Application to Register Permanent Residence or Adjust Status. Individuals filing these forms together will continue to mail them to the Chicago Lockbox facility. Petitioners filing from overseas addresses in countries without USCIS offices will also continue to file at the Chicago Lockbox facility. Petitioners residing in a country with a USCIS office may send their I-130 forms to the Chicago Lockbox, or they may file their Forms I-130 at the international USCIS office having jurisdiction over the area where they live. Customers should ensure they are filing at the proper location. Individuals who submit their Form I-130 packages to the incorrect Lockbox location may experience a delay in processing. Questions or concerns regarding where to file your application should be directed to the USCIS National Customer Service Center at 1-800-375-5283.
