IOM works on the development of policy guidance for the field; the formulation of global strategies; standard-setting and quality control; and knowledge management relating to “mainstream” migration sectors, including labour and facilitated migration, migration and development, counter-trafficking, assisted voluntary return, migration health, assistance for vulnerable migrants, immigration and border management and overall capacity-building in migration management.

IOM’s Department of Migration Management also manages the IOM Development Fund and is responsible for reviewing, endorsing and managing multiregional and global projects. The Department provides technical supervision of project review and endorsement to experts in the field. It is also responsible for maintaining operational partnerships with relevant governmental, multilateral and private sector industry partners in coordination with the Department of International Cooperation and Partnerships.

In Germany, IOM's main activities are based in the area of migrant protection and assistance, including Assisted Voluntary Return and Reintegration, support of vulnerable migrants, services regarding Resettlement and humanitarian admissions as well as immigration assistance. In close cooperation with the German government and partners from civil society, research, politics and migrant communities, IOM implements projects and advocates for migrants' rights.
