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

The U.S. Customs and Border Protection app, called CBP Home, will offer an option for someone to signal their "intent to depart," the agency said.

The new app, CBP Home offers undocumented immigrants a way to signal their intent to leave the US, potentially avoiding arrest and detention.
