Alireza Doroudi, a doctoral student in mechanical engineering at the University of Alabama from Iran, was detained by ICE agents on March 25, 2025, around 3-5 a.m. at his home after the State Department revoked his F-1 student visa. Doroudi had entered the U.S. in January 2023 and his visa was revoked six months after arrival, though university international student services advised he could remain legally if he maintained student status. DHS cited national security concerns as the basis for the detention and visa revocation, but provided no specific allegations. Doroudi's immigration attorney stated he is unaware of any such concerns. He is being held at the Jena/LaSalle Detention Facility in Louisiana.
