The Diplomatic Security Service, or DSS, is a division of the US Department of State. The DSS protects high-level diplomats when they visit the United States, except heads of state who are protected by the Secret Service. DSS also has investigative and administrative responsibilities. DSS frequencies have been observed in use at regional Passport Agency Offices.
