Green card holder's rights questioned after protester’s arrest

Mahmoud Khalil, a green card holder and former Columbia University student, was arrested by immigration agents in New York on March 8. He is being held in Louisiana without charges, raising concerns about the rights of permanent residents. Green card holders can be deported for various reasons, including criminal activity or perceived threats to U.S. foreign policy. They have due process rights, but their status can be revoked without a criminal conviction under certain circumstances. Khalil's arrest is justified by the Trump administration using a provision of the Immigration and Nationality Act related to foreign policy. His attorneys argue that his detention is illegal and an infringement on his rights to lawful dissent.
