A new report reveals that the State Department is planning to cancel the visas of thousands of Chinese students studying in the United States.

According to The Daily Caller:

The U.S. is reportedly taking action to expel Chinese graduate students over national security concerns.

The initiative has been in the works for several months, but received new life after China imposed national security restrictions on Hong Kong, according to the New York Times. Secretary of State Mike Pompeo claimed China’s “disastrous decision” undermines “Hong Kong’s autonomy and freedoms and China’s own promises to the Hong Kong people.”

Pompeo reportedly discussed the visa cancellations with White House officials Tuesday. The move is estimated to result in the expulsion of at least 3,000 students, all with reported direct ties to the Communist Party of China. In total, there are roughly 360,000 Chinese students enrolled in the American university system.

A senior State Department official declined to comment directly on the details of NYT’s reporting but added the decision is up to the White House at this point.

Lawmakers have also drafted legislation in Congress that would block Chinese graduate and post-graduate from receiving visas if they are studying science, technology, engineering, and mathematics (STEM).
