As countless asylum hearing appointments were canceled Monday, those who had already trekked across the McAllen-Hidalgo International Bridge on the day Trump was inaugurated underwent three-hours of processing before making their their way to shelters and other temporary housing.

President Donald Trump on Monday officially shut down the Customs and Border Protection-run app designed to help schedule appointments for people seeking eligibility for asylum, closing off a pathway for migrants at the Southern border hoping to enter the United States.

Just as Donald Trump's inauguration concluded, Honduran asylum seeker Denia Mendez's phone buzzed with alarming news: the CBP One app, her lifeline to a new life in the US, was down.

The CBP One app, a government platform that the Biden administration used to admit more than 740,000 immigrants into the United States, was shuttered within moments of President Donald Trump taking office this afternoon.

The CBP One app has been wildly popular. It is an online lottery system to give appointments to 1,450 people a day at eight border crossings.

CBP One was launched in 2020, allowing foreign vendors to schedule cargo inspections. In 2023 the Biden administration expanded its functions to include unauthorized migrants seeking asylum. This Monday, on Inauguration Day, an order from Donald Trump put an end to the program, and thousands of scheduled appointments were canceled.

On the day of President Donald Trump's inauguration, the government application CBP One, which migrants used to submit a legal visa application, ceased functioning. The CBP One application was introduced by Joe Biden's administration to reduce illegal crossings of the Mexico-US border.
