The Trump administration is planning to dismiss asylum claims for potentially hundreds of thousands of migrants in the United States and then make them immediately deportable as part of the president’s sweeping immigration crackdown, according to two sources familiar with the matter.

It marks the latest in a series of moves by the administration to bar migrants from receiving protections in the US. As federal authorities come under pressure to deliver historic immigration arrest numbers, administration officials have quietly been working on efforts to make more people eligible for removal.

The people being targeted in this case are those who entered the US unlawfully and later applied for asylum, the sources said. Their cases are expected to be closed, therefore leaving them at risk of deportation. It could affect hundreds of thousands of asylum applicants.

Over the last decade, the majority of applicants who applied for asylum with US Citizenship and Immigration Services, or USCIS, self-reported how they entered the US, with around 25 percent saying they entered the US unlawfully. That amounts to at least a quarter of a million people, according to a federal report analyzing asylees in 2023. The others entered legally via a port of entry through various visas.

Under US law, people who are seeking protection from violence or persecution in their home country can claim asylum to remain in the United States. Trump effectively sealed off access to claiming asylum at the US southern border upon taking office.
