The Regional Security Office is a part of the Diplomatic Security Service, or DSS (https://www.state.gov/bureaus-offices/under-secretary-for-management/bureau-of-diplomatic-security/), which is the law enforcement arm of the U.S. State Department.

DSS was founded in 1916 as the Office of the Chief Special Agent. It assumed its current title in 1986. A Federal law enforcement organization, the DSS is represented domestically and in U.S. Embassies and Consulates overseas. DSS has Special Agents assigned to domestic field offices throughout the United States as well as over 155 countries. No other Federal law enforcement entity is more broadly represented globally than the agents of the Diplomatic Security Service.

Domestically, DSS agents are responsible for the protection of the Secretary of State, foreign diplomatic missions and visiting foreign dignitaries. Additionally, they conduct investigations into violations of U.S. passport/visa laws and false identity crimes.

Overseas, DSS agents serve in U.S. Embassies and Consulates as the mission’s Regional Security Office (RSO). The agents serve as the Ambassador’s principal adviser on terrorism and criminal, counter-intelligence, and security matters. Additionally, they conduct investigations on behalf of U.S. federal, state and local law enforcement agencies. Among other activities, the RSO also is responsible for the Overseas Security Advisory Council (http://www.osac.gov/) and Rewards for Justice (http://www.rewardsforjustice.net/) programs.

Experienced in serving both domestically and abroad, Special Agents of the Diplomatic Security Service provide a unique service to the citizens of the United States. They take pride in the motto “Serving America Around the World.”
