Please note that this restriction does not apply to all international passengers.The application is then forwarded to the appropriate US Consulate or Embassy overseas for further processing and, if eligible, issuance of the immigrant visa to the intending immigrant. Before the immigrant visa expires, the intended immigrant must show the immigrant visa at a U.S. port-of-entry. When an immigrant's immigrant visa is approved, he or she becomes a lawful permanent resident.
