Biden unveils Trump-style plan to deter asylum seekers at Mexico border

Administration's most aggressive plan yet would bar most migrants who hadn't sought protection in other countries first

The United States could bar tens of thousands of migrants arriving at the US-Mexico border from claiming asylum under a proposal unveiled on Tuesday that would be the most wide-ranging attempt yet by Joe Biden's administration to deter unauthorized crossings.

Under the new rules, the US would generally deny asylum to migrants who show up at the US southern border without first seeking protection in a country they passed through, mirroring an attempt by the Trump administration that never took effect because it was blocked in court.
