Several migrants said they had recently arrived in Ciudad Juarez, Mexico after weeks of travel, only to find their CBP One appointments were cancelled.

President Donald Trump's promises of mass deportations, which could bring batches of new arrivals fresh off the border bridges into Juárez, has Mexican law enforcement preparing to keep watch for potential trouble.

Hours after Trump’s inauguration, his administration canceled appointments allowing migrants to enter the U.S. to request asylum, leaving many of them stranded on the U.S.-Mexico border.
