This number is no longer in service.

A Biden-approved phone app that allowed up to 1,450 undocumented aliens per day to enter the U.S. on “parole,” including the ability to work, has ended.

Within minutes of Donald Trump taking the oath of office, a notice appeared on the U.S. Customs and Border Patrol website that the CBP One app is no longer available and all existing appointments have been canceled, the Associated Press reported.

The app allowed nearly 1 million people to enter the U.S., according to AP, part of a flood of illegal immigration under Biden.

Trump, a Republican, has promised numerous crackdowns on immigration, as well as efforts to deport illegal immigrants who have committed crimes.
