“ICE HSI (Homeland Security Investigations) made this arrest in accordance with the State Department’s revocation of Doroudi’s student visa. This individual posed significant national security risk concerns,” the statement read. According to The Crimson White, the DHS spokesperson did not explain what those national security risk concerns entailed.

Alireza Doroudi's detention comes as the Trump administration has moved to revoke visas for hundreds of noncitizen students across the U.S.

Federal immigration agents have detained a University of Alabama doctoral student who is a citizen of Iran, according to the school and ICE records.
