The Biden administration has finalized a sweeping restriction on asylum that will disqualify migrants from U.S. protection if they fail to request refugee status in a third country before arriving in the United States. The regulation is intended to discourage illegal immigration and protect the safety of migrants, while also reducing the backlog of asylum cases in the U.S. immigration system. Hundreds of U.S. asylum officers have been trained to enforce the restriction and it is expected to be published on Wednesday, just before Title 42 is set to expire.
