Victoria Meijia Garcia, 31, opened the CBP One app at 10 a.m. Monday as she did every day for the past several months, seeking an available appointment with an asylum official. But today, the top of the familiar homepage blared a message that filled her with dismay.

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.

CBP One was used by the Biden administration to allow hundreds of thousands of migrants into the country to pursue asylum claims.

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.

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.

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.

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.
