From a recent email from Lutheran Social Services of the Southwest:
In 2018, the U.S. Customs and Border Patrol processed more than 107,000 migrant families seeking asylum and protection. With ICE lacking the capacity for growing asylee numbers, families have been released to churches in Phoenix for temporary and transitional shelter until they are capable of traveling to their final destination. Currently, there are not enough churches to accommodate the increasing numbers of asylum-seekers, and these families are being released on the street and at bus stations, with no means to continue their journey.
