An immigrant (also called a "lawful permanent resident") is a foreign national who has been granted the privilege of living and working permanently in the United States. Your sibling must go through a multi-step process to become an immigrant. First, the U.S. Citizenship and Immigration Services (USCIS) must approve an immigrant visa petition that you file for your brother or sister. Second, the State Department must give your brother or sister an immigrant visa number, even if your brother or sister is already in the United States. Third, if your brother or sister is already in the United States, your brother or sister may apply to adjust to permanent resident status after a visa number becomes available. If your brother or sister is outside the United States when an immigrant visa number becomes available, your brother or sister will be notified to go to the local U.S. Consulate to complete the processing for an immigrant visa.
