Columbia University arrests worry international college students

International students and foreign faculty have watched the crackdown on pro-Palestinian protesters at Columbia University with apprehension. Some say they are familiar with government crackdowns but never expected them on American college campuses. Federal immigration agents have arrested two foreigners who took part in protests last year at Columbia. They’ve revoked the visa of another student, who fled the U.S. Agents also searched the on-campus residences of two Columbia students on Thursday but did not make any arrests there. International students say they feel afraid to voice opinions or stand out on campus for fear of getting kicked out of the country.
