HONG KONG (AP) — Chinese students studying in the U.S. are scrambling to figure out their futures after U.S. Secretary of State Marco Rubio announced Wednesday that some students would have their visas revoked. The U.S. will begin revoking the visas of some Chinese students, including those studying in “critical fields", and "those with connections to the Chinese Communist Party," according to the announcement. China is the second-largest country of origin for international students in the United States, behind only India.
