The organization's global mandate includes assistance to migrants, including migrant workers, refugees and internally displaced persons. This broad mandate of the organization has earned it praise for flexibility in crisis situations, Due to complementary mandates, IOM often cooperates with the
UNHCR. For example, IOM coordinates work in response to the situation in Venezuela through the
Office of International Organization for Migration Director General's Special Envoy for the Regional Response to the Venezuela Situation working with
UNHCR and 17 countries in South and Central America and the Caribbean. According to the
United Nations Office for the Coordination of Humanitarian Affairs (OCHA), IOM is one of the central actors in humanitarian aid within the UN system, especially in the context of displacement. IOM's main aid measures include shelter, protection, the provision of basic medical and sanitary care, life safety, coordination, telecommunications and logistics. On the instructions of the
UN Emergency Relief Coordinator, IOM, together with UNHCR, is primarily responsible for camp coordination and management in humanitarian emergencies. The organization is also active in stabilization, peacebuilding and development in the context of migration. In 2026, IOM announced its co-leadership, together with the International Federation of Red Cross and Red Crescent Societies (IFRC), of the Shelter, Land and Site Coordination Cluster, guiding coordination for humanitarian shelter, land and site management worldwide.
