More than a million migrants who were allowed to enter the United States during the Biden administration can have their temporary stays revoked and be rapidly deported, according to an Immigration and Customs Enforcement document that became public Friday.

The U.S. Department of Homeland Security memo provides guidance for the use of a fast-track deportation process that the Trump administration reinstated earlier this week, suggesting officers focus on migrants who failed to request asylum within a one-year deadline after arriving in the U.

Migrants allowed into the U.S. temporarily under certain Biden administration programs can be quickly expelled, according to a memo sent by the Trump administration's acting secretary of homeland security.

The acting head of the Department of Homeland Security (DHS) is allowing immigration enforcement agents to swiftly deport those who came to the U.S. under multiple pathways established under the Biden administration.

ICE agents have reportedly been issued a "road map on how to use expansive powers that were long reserved only for encounters at the southern border."
