Harvard’s leadership has asked a court to stop the Trump administration’s latest attempt to block international students — over a fourth of its student body — from coming to the university, according to a new court filing less than 24 hours after the latest move by President Donald Trump against the university.

Harvard University on Thursday expanded a lawsuit against the US government's decision to block international students from attending the elite institution. On Wednesday, US President Donald Trump signed a proclamation suspending international visas for students due to national security concerns and their failure to comply with federal agencies.
