Uyghur Stop Oppressive Sterilizations Act or the Uyghur SOS Act This bill expands existing visa-blocking sanctions to cover certain high-ranking foreign government officials who are responsible for coercive population control policies, such as forced abortions, with a focus on those responsible for such policies against ethnic minority groups in China. Specifically, the Department of State may not issue a visa to a foreign national who is a head of state, head of government, or cabinet-level minister and responsible for establishing or enforcing such policies if the policies are (1) imposed with the intent to destroy a national, ethnic, racial, or religious group; or (2) targeting ethnic minority groups (e.g., Uyghurs, Kazakhs, or Tibetans) or individuals peacefully expressing internationally-recognized human rights in China. (Currently, these sanctions do not apply to any foreign government officials at these higher ranks.) The State Department must make a public announcement each time sanctions are imposed under this bill. The bill also requires the State Department to provide all appropriate assistance to women who belong to an ethnic minority group in China and who have experienced sexual violence, torture, or coercive population control policies.
