The Diplomatic Reserve Corps Act of 2026 aims to establish a new group within the U.S. Department of State, known as the Diplomatic Reserve Corps, to enhance the Department's capabilities in international relations. This initiative will create a pool of trained personnel who can assist the Secretary of State and the Foreign Service in various diplomatic operations. The Act outlines the formation of the Corps, which will consist of four components: the Senior Diplomatic Reserve, the Senior Diplomatic Retiree Reserve, the Diplomatic Reserve, and the Diplomatic Retiree Reserve.
