Instituto del Servicio Exterior de la Nación

The Instituto del Servicio Exterior de la Nación ("Foreign Service Institute of the Nation", ISEN), is the Argentine government's training institution for employees of the diplomatic service. It is dependent on the Ministry of Foreign Affairs and Worship. Its goals are to select and train Argentine diplomats and other employees of the diplomatic service so they may advance the Argentine foreign affairs agenda, as well as to produce knowledge on current international affairs.

Since its foundation in 1963, it has served as the only institution for selecting and training diplomatic professionals in Argentina. ISEN graduates are granted "diplomatic state" for life, meaning they must follow the responsibilities laid out in Argentine diplomatic law even after retirement.
