The Trump administration is preparing to revoke legal status for many migrants who entered the United States under a Biden-era program, according to a source familiar with the planning, expanding the pool of people who could be deported.

The DHS proposal would terminate a Biden administration program that allowed more than 530,000 Cubans, Haitians, Nicaraguans and Venezuelans to fly to the U.S.

This will revoke legal entry for over 530,000 and initiate deportation for those without additional immigration benefits.

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.
