A Louisiana immigration judge has ruled that the U.S. can deport Mahmoud Khalil based on the federal government’s argument that he poses a national security risk. His lawyers are expected to appeal, and a federal judge in New Jersey has temporarily barred Khalil’s removal from the country.

While an immigration judge’s ruling that Columbia University graduate Mahmoud Khalil – a legal permanent resident – can be deported is a victory for the Trump administration, the legal fight against his detention and deportation is far from over.

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