Yet more thoughts on the Trump administration’s decision to more tightly control student visas:
In late May, the Trump administration announcedthat the length of visas for Chinese graduate students working in certain fields would be cut to one year. Not unexpected, the step is intended to protect advanced U.S. technology from Chinese appropriation, as well as limit the speed of Chinese technological advances. The practical impact of the change remains uncertain, and relatively few students will actually see a change; for the most part it may simply add to the hassle and paperwork that these students face.
As with the other steps against China, there seems to be a real punitive effort here.
