JUAREZ, MEXICO — The Biden administration is grappling with a huge logistical and humanitarian challenge on the Southwest border, where about 5,000 unauthorized migrants are crossing on average every day.

About half of the migrants are allowed to stay in the U.S. and ask for asylum, and the rest are turned back to Mexico, according to a senior Border Patrol official who spoke on condition of anonymity to reporters on Friday.
