In order for a child adopted abroad to enter the U.S., the parent(s) must petition
            the Department of Homeland Security, United States Citizenship and Immigration Services
            (DHS, USCIS) to have the child classified as an immediate relative for the purpose
            of bringing the child into the United States. Before they determine that the child
            meets immigrant classification code of IR3/IH-3, or IR2 and may be legally admitted
            to the United States, DHS, USCIS and the Department of State determine that the child
            has been fully and finally adopted in compliance with the laws of the country where
            the adoption took place.
         
         For the purpose of establishing a valid foreign adoption, the immigrant classification
            code of IR7 is equivalent to IR2.  IR2 denotes a new arrival to the country while
            IR7 denotes a person whose status was adjusted after admission to the U.S.
         
         Children admitted with IR-4/IH-4 visas may or may not have completed the adoption process abroad. If the adoption process was not completed
            abroad, then parents will need to take the additional steps to complete the adoption
            process after arriving in the U.S. The issuance of documents showing the IR-4/IH-4
            status is not evidence alone that the child was fully and finally adopted in the foreign
            country.
         
         Since January 20, 2004, DHS, USCIS automatically issues a Certificate of Citizenship
            to a foreign-born adopted child when the child is admitted to the U.S. and meets the
            requirements of the Child Citizenship Act of 2000. Prior to that date the parents
            were required to apply for proof of the child's citizenship, either to DHS (for a
            Certificate of Citizenship) or to the Department of State (for a U.S. passport).
