The IGC is an informal, non-decision making forum for intergovernmental information exchange and policy debate on issues of relevance to the management of international migratory flows.

The IGC brings together 16 Participating States, the United Nations High Commissioner for Refugees, the International Organization for Migration and the European Commission. The Participating States are Australia, Belgium, Canada, Denmark, Finland, Germany, Greece, Ireland, Netherlands, New Zealand, Norway, Spain, Sweden, Switzerland, United Kingdom and United States of America.

IGC engages on issues across the migration spectrum and supports strategic thinking and the development of policy options by:

• organising meetings, roughly 20 senior official and expert meetings per year,
• fostering policy and operational expert networks across the globe,
• providing access to state-owned policy guidance, analytical reports and studies, and
• developing and maintaining on-line information exchange tools and statistical databases.
