The International Organization for Migration (IOM) is a leading intergovernmental organization that promotes safe, orderly, and humane migration worldwide. Its role is to assist in meeting the growing operational challenges of migration, advance understanding of migration issues, encourage social and economic development through migration, and uphold the human dignity and well-being of migrants and their families.

Some of the specific roles of the IOM include:

1. Providing humanitarian assistance to migrants in need, including emergency response and resettlement support.
2. Supporting governments in managing migration through policy development, technical assistance, and capacity building.
3. Conducting research and analysis on migration trends and issues, and sharing information and best practices with governments and other stakeholders.
4. Facilitating the orderly and safe migration of people, including through migration services such as pre-departure health assessments and assistance with visas and travel arrangements.
5. Advocating for the rights and well-being of migrants, including by promoting policies and practices that protect their rights and combat discrimination and exploitation.

IOM plays a crucial role in promoting safe, orderly, and humane migration, and supporting governments and other stakeholders in managing the complex challenges of migration in a responsible and sustainable way.
