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

The Department of Homeland Security has empowered federal immigration officials to bypass protections for hundreds of thousands of migrants who entered the country legally through Biden administration programs and begin immediate and rapid deportations,

The Trump administration is powering ahead with efforts to ramp up immigration enforcement, opening up the possibility of targeting migrants who entered through Biden-era programs and invoking an obscure immigration statute to make it easier to deputize state and local law enforcement to arrest and detain immigrants in the U.

The Department of Homeland Security says it is continuing to accept requests for asylum-seekers arriving at the U.S.-Mexico border, and is authorizing travel for certain nationals of Cuba, Haiti, Nicaragua and Venezuela seeking to lawfully enter the United States through a humanitarian parole program beyond Jan.

The far-reaching move empowers federal immigration agencies to target a population of migrants who came to the U.S. with the government's permission.
