The US-Mexico border is effectively closed off to migrants seeking asylum in the United States within hours of President Donald Trump taking office, an extraordinary departure from previous protocols that has left many concerned migrants in limbo.

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.

Trump’s efforts to stop a so-called ‘invasion’ of migrants could imperil relations with the US’s biggest trading partner, Mexico.

Nidia Montenegro fled violence and poverty at home in Venezuela, survived a kidnapping as she traveled north into Mexico, and made it to the border city of Tijuana on Sunday for a U.S. asylum appointment that would finally reunite her with her son living in New York.

President Donald Trump has issued a “full and unconditional pardon” to Washington, DC, police lieutenant Andrew Zabavsky and officer Terence Sutton for their roles in the death of 20-year-old Karon Hylton-Brown, a case that drew protests on the heels of the murder of George Floyd.

Migrants at the US-Mexico were seen bursting into tears after being told that their asylum appointments had been canceled immediately after Donald Trump was sworn in as the 47th President. CBP One is the app that allows tens and thousands of migrants to apply for appointments to enter the United States.
