Foreign Service specialist
A Foreign Service specialist (FSS) is direct-hire career employee of the United States Department of State or another foreign affairs agency. Legally established as "foreign service personnel," one of the seven member categories of the United States Foreign Service, they are informally known as "specialists" to distinguish them from "officers" who are a different category in the service. They are members of the United States Foreign Service who provide important technical, support, or administrative services in nineteen career categories, including diplomatic security special agents, doctors and physician assistants, diplomatic technology officers, office management specialists, and human resource specialists. They serve in over 290 embassies or consulates abroad, Washington, D.C. or other locations in the continental United States.
