The United States Secret Service (USSS)

The United States Secret Service (USSS) performs two critical homeland security missions: protection and criminal investigation. Through its protective mission, the Secret Service preserves continuity of government and ensures security at events of national significance by protecting the President and Vice President, their families, visiting heads-of-state/government, and other designated individuals. The USSS also investigates threats against these protectees; protects the White House, the Vice President's Residence, Foreign Missions, and other designated buildings within the Washington, D.C. area; and designs, coordinates, and implements operational security plans for designated National Special Security Events .

Through its investigative mission, the USSS prevents cyber crime and other malicious uses of cyberspace that can create economic instability and undermine confidence in U.S. financial systems. The Secret Service does this by investigating violations of laws relating to: counterfeiting of obligations and securities of the United States; financial crimes, such as access device fraud, financial institution fraud, identity theft, and computer fraud; and computer-based attacks on our nation's financial, banking, and telecommunications infrastructure.

In order to fulfill its protective and investigative mission, the Secret Service maintains both domestic and international offices and employs special agents, uniformed officers, and support personnel.

The USSS Moscow Resident Office is responsible for the coordination of international investigations and protective visits with its Russian counterparts. The USSS Attaché cultivates and maintains a close liaison with law enforcement, intelligence and security services throughout its geographic area of responsibility.
