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.

CBP One, a border app that has allowed nearly 1 million people to legally enter the United States with eligibility to work, was abruptly shut down on Monday, shortly after President-elect Donald Trump took office.

On his first day in office, President Trump shut down the CBP One mobile application that facilitated the legal entry of migrants into the U.S. at certain ports of entry. Why it matters: Thousands of people are left stranded in Mexico,

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, used by migrants to notify the U.S. government of their intention to arrive at a port of entry and provided resources, has been shut down by the Trump Administration.

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.
