Vahid Abedini, an OU College of International Studies professor with an employer-sponsored H-1B visa, was detained by ICE for three days after being stopped at Will Rogers Airport in November while preparing to travel to an academic conference. Federal authorities said the detention was for standard questioning, though Abedini was asked very few questions according to colleagues. He has since been released but remains fearful of retaliation and has limited his public comments about the incident.
