U.S. Will ‘Aggressively’ Revoke Visas of Chinese Students, Rubio Says

Secretary of State Marco Rubio announced on Wednesday evening that the Trump administration would work to “aggressively revoke” visas of Chinese students, including those with ties to the Chinese Communist Party or who are studying in “critical fields.”

He added that the State Department was revising visa criteria to “enhance scrutiny” of all future applications from China, including Hong Kong.

The move was certain to send ripples of anxiety across university campuses in the United States and was likely to lead to reprisal from China, the country of origin for the second-largest group of international students in the United States.

Mr. Rubio’s brief statement announcing the visa crackdown did not define “critical fields” of study, but the phrase most likely refers to research in the physical sciences. In recent years, American officials have expressed concerns about the Chinese government recruiting U.S.-trained scientists, though there is no evidence of such scientists working for China in large numbers.

Similarly, it is unclear how U.S. officials will determine which students have ties to the Communist Party. The lack of detail on the scope of the directive will no doubt fuel worries among the roughly 275,000 Chinese students in the United States, as well as professors and university administrators who depend on their research skills and financial support.
