Trump shuts down CBP One app use by illegal aliens to enter country, cancels remaining appointments | 20 Jan 2025 | Shortly after taking office, President Donald Trump ended the use of the CBP One App used by illegal migrants to enter the U.S., and canceled all remaining appointments made through the software. "Effective January 20, 2025, the functionalities of CBP One that previously allowed undocumented aliens to submit advance information and schedule appointments at eight southwest border ports of entry is no longer available, and existing appointments have been cancelled," the Customs and Border Protection agency's website reads. The CBP One app allows migrants to schedule asylum appointments with U.S. immigration officials once they reach Mexico City or states in northern Mexico. The app has come under scrutiny in the past from Republicans, with some stating it has been used to hide illegal immigration.
