Donald Trump's latest crackdown has triggered a legal and diplomatic storm, with Harvard University and thousands of international students caught in the crossfire. Among them are Cleo Carney, daughter of Canada’s Prime Minister Mark Carney,

On May 22, Secretary of the Department of Homeland Security Kristi Noem ordered the Department of Homeland Security to terminate Harvard University’s Student and Exchange Visitor Program (SEVP) certification, meaning "Harvard can no longer enroll foreign students and existing foreign students must transfer or lose their legal status."

Another high-profile student caught between the crosshairs is Princess Elisabeth of Belgium. She is the heir to the Belgian throne and has just completed her first year in a two-year masters program in public policy at the Harvard Kennedy School.
