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 US Coast Guard is taking President Donald Trump’s anti-immigrant mandate seriously, announcing this week it will step up patrols in migrant-prone crossings.

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.

Under the Biden administration, migrants from embattled countries could apply for entry for humanitarian reasons, without having to attempt to cross into the U.S. illegally.

The president sought to end a program that allowed migrants fleeing Cuba, Nicaragua, Venezuela and Haiti to fly into the United States and remain in the country for up to two years.

We’re evaluating and talking about that right now,’ Kristi Noem said on Fox News on Wednesday morning. ‘It’s the president's decision.’

President Trump has ended programs that brought nearly a million and a half people from Cuba, Haiti, Venezuela and Nicaragua. The legal status of these immigrants, who often fled violence and war, is now in jeopardy. We get the latest from NPR's Sergio Martínez-Beltrán.

For weeks, lawyers and advocates, worried about President Donald Trump’s promised immigration crackdown, have been telling asylum seekers and migrants temporarily paroled into the United States to keep their documents with them at all times in case they are stopped by overzealous cops or immigration agents.

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

Immigration officials now have permission to quickly expel migrants temporarily admitted via the CBP One App and a separate program for certain people fleeing Cuba, Haiti, Nicaragua and Venezuela.

Since CBP One app was fully rolled out in January 2023, more than half a million immigrants have been admitted into the United States.
