The International Organization for Migration (IOM) is a United Nations agency that provides services and advice concerning migration to governments and migrants, including internally displaced persons, refugees, and migrant workers. The IOM was established in 1951 as the Intergovernmental Committee for European Migration (ICEM) to help resettle people displaced by World War II. It became a United Nations agency in 2016. The IOM is the principal UN agency working in the field of migration. The IOM promotes humane and orderly migration by providing services and advice to governments and migrants.
