Immigration officials may deport migrants to countries other than their own with as little as six hours' notice, Trump administration memo says.

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.
