The Department of Homeland Security is opening the door to the parole status of migrants to be reviewed, leading to their eventual removal from the country.

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

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."

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.

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.
