Migrants in Mexico who were hoping to come to the U.S. are adjusting to a new and uncertain reality after President Donald Trump began cracking down on border security.

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.

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