File at the Chicago or Phoenix Lockbox, depending on where you live and whether you are also filing Form I-485, Application to Register Permanent Residence or Adjust Status. If you reside outside of the United States where USCIS has an international office
, you may file at the USCIS Chicago Lockbox facility or at the USCIS international office in the country in which you reside. If you reside outside of the United States where USCIS does not have an international office, you may file at the U.S. Embassy or consulate having jurisdiction over the area where you live only if exceptional circumstances
exist and the USCIS Field Office Director with jurisdiction over that location determines that the Embassy or consulate may accept and adjudicate the case.
