Approved International Organizations

A federal agency may detail or transfer an employee to any organization that the Department of State has designated as an international organization on the list below.  The list below does not determine whether an entity is an international organization for the purpose of other statutes or regulations, it is solely for the purpose of detailing or transferring federal employees.  It will be updated as new organizations are added or deleted.  Please visit our Federal Agency and Federal Employee pages to learn more about how the detail and transfer process works.

While the U.S. government participates in other international organizations not listed here, the degree of participation may not be enough to warrant designating the organization an international organization for the purpose of details and transfers.  The Department of State will consider the status of such organizations under the detail and transfer statutory provisions on a case-by-case basis when requested to do so by Federal agencies.

Federal agencies interested in learning more about how to add an organization to the list should contact us for information on the process.
