How the Trump administration is expanding its crackdown on international college students

A crackdown on foreign students is alarming colleges, who say the Trump administration is using new tactics and vague justifications to push some students out of the country.

College officials worry the new approach will keep foreigners from wanting to study in the U.S.

Students stripped of their entry visas are receiving orders from the Department of Homeland Security to leave the country immediately—a break from past practice that often permitted them to stay and complete their studies.
