Khalil, 30, was the first international student arrested in recent weeks amid an unprecedented crackdown by federal immigration authorities.

A federal judge on Friday ruled that the Trump administration can deport Columbia University graduate student Mahmoud Khalil just a month after his arrest prompted national outrage and marked the start of the federal government’s broader crackdown on foreign students.

Khalil has until April 23 to file for relief.

In his ruling the judge said, “the court will sustain charge of removability.”
