Hours before sunrise, migrants at one of Mexico’s largest shelters wake up and go online, hoping to secure an appointment to try to seek asylum in the U.S. The daily ritual resembles a race for concert tickets when online sales begin for a major act, as about 100 people glide their thumbs over phone screens.
New appointments are available each day at 6 a.m., but migrants find themselves stymied by error messages from the U.S. government's CBPOne mobile app that's been overloaded since the Biden administration introduced it Jan. 12.
