The International Office of the European Student Think Tank is the body with representation from ambassadors in EU member states. The International Office oversees our team of Ambassadors. The EST Ambas­sad­ors are the link between the EST and the EU’s mem­ber states and offi­cial can­did­ate mem­ber states. They rep­res­ent the EST, pro­mote and organ­ize events loc­ally, write blogs about their country and make sure our net­work is as big as pos­sible.
