The lifting of Title 42.

SOMERTON, AZ - MAY 12: Migrants who have been processed by U.S Border Patrol and have been released from their center, are given assistance from the Regional Center for Border Health to relocate to areas outside of Yuma, on Friday, May 12, 2023 in Somerton, AZ. Roughly 800 migrants were assisted today by the Regional Center for Border Health. Title 42, a pandemic-era policy that allowed border agents to quickly turn back migrants, expires this week. Under a new rule, the U.S. on Thursday will begin denying asylum to migrants who show up at the U.S.-Mexico border without first applying online using the CBP One mobile application or seeking protection in a country they passed through.
