IV. United States Information Service

USIA operations overseas were handled by the United States Information Service (USIS). USIS began operation as the overseas arm of the Office of War Information during World War II and continued after the war until August 1953 under the auspices of the Department of State, when it became the overseas arm of the United States Information Agency (USIA). When USIA was abolished in 1999, USIS once again fell under the Department of State.

Information about USIS records is found under the section covering Department of State Foreign Service Post records (RG 84).  See this report for a list of extant USIS records accessioned and processed as of January 2017.
