Migrants form lines outside the border fence waiting for transportation to a U.S. Border Patrol facility in El Paso, Texas, Wednesday, May 10, 2023. President Joe Biden’s administration on Thursday will begin denying asylum to migrants who show up at the U.S.-Mexico border without first applying online or seeking protection in a country they passed through, according to a new rule released Wednesday, as U.S. officials warned of difficult days ahead as a key limit on immigration is set to expire.
