U.S. Immigration and Customs Enforcement will generally wait at least 24 hours to deport someone after informing them of their removal to a so-called "third country," according to a memo dated Wednesday, July 9, from the agency's acting director, Todd Lyons.

Under the memo, first reported by the Washington Post, ICE is now authorized to deport non-citizens — including long-term U.S. residents — to third countries with only 24 hours’ notice. In “exigent circumstances,” that window can shrink to six hours, so long as the detainee is given an opportunity to speak with an attorney.

New ICE policy allows deportation of migrants to third countries with only six hours’ notice following a Supreme Court ruling.
