Where Biden and Trump differ - and overlap - on immigration policy

Under current law, any foreign national arriving to the US can claim asylum. But both the Biden and Trump administrations have sought to control the number of those making that claim through policies such as the Covid-era Title 42 and the "Remain in Mexico" programme.

During his successful White House bid, Mr Biden campaigned against Mr Trump's restrictive asylum policies, particularly the "transit ban" that forbade migrants from applying for asylum unless they first applied before they reached the US border.

Faced with mounting criticism, however, the Biden administration and Democratic allies have suggested asylum provisions similar to Mr Trump's.

A stalled bipartisan border bill, for example, would have tightened asylum restrictions and created daily limits on border crossings. Once that capped was reached, asylum seekers would have been turned away.
