America can guard its core technologies, but relinquishing its status as an international education hub will undermine its global influence

While the US has resumed processing of student and exchange visitor visas, the future of Chinese students who are attending Harvard remains uncertain.

The resumption followed a federal judge’s decision last week to temporarily block a ban on Harvard’s qualification to enroll international students.

In a phone call last week with Chinese President Xi Jinping, Donald Trump said the “US loves to have Chinese students coming to study in America”.

Earlier, Trump said he welcomed Chinese students, but not those who caused “troubles”. It is still not clear what he meant.
