The memo, signed by the acting director of ICE, Todd Lyons, and dated May 12, 2025, says: “Although the U.S. Department of Homeland Security (DHS) has not historically relied on administrative warrants alone to arrest aliens subject to final orders of removal in their place of residence, the DHS Office of the General Counsel has recently determined that the U.S. Constitution, the Immigration and Nationality Act, and the immigration regulations do not prohibit relying on administrative warrants for this purpose.”
