A memo appears to allow Immigration and Customs Enforcement officials to target programs that let in more than a million people.

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.

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

The Biden administration had extended protections for more than 600,000 Venezuelans. The cancellation of the extension could open them up to deportation in the coming months.
