Critics of the Biden-era CBP One app said migrants were abusing the asylum-request system to legally enter the United States, then disappear.

President Donald Trump repurposed the app. Rather than facilitating immigration, CBP Home, as CBP One has been rebranded, plans to facilitate “self-deportation.” “

CBP Home is a phone app previously used for people seeking asylum in the U.S. But, it has since been revived with a different purpose.
