The Stop Scamming Americans Act amends the Foreign Service Act of 1980 to require the State Department to establish training programs for U.S. diplomats being assigned to countries with significant online scam operations targeting Americans. The training would cover transnational criminal organizations running these scams, the operations of online scam centers and human trafficking within them, and instances of foreign government complicity or corruption. The legislation is designed to help U.S. ambassadors, deputy ambassadors, and Foreign Service officers understand and combat these criminal activities through diplomatic channels. The bill does not specify funding amounts or implementation timelines, leaving those details to the Secretary of State's discretion.
