Title 42 expiration sparks uncertainty and chaos at US-Mexico border.

The Biden administration has finalized a new asylum restriction that will disqualify most non-Mexican migrants who enter the U.S. between ports of entry from asylum, if they fail to request refugee status in another country, such as Mexico, on their journey to the southern border. The regulation is expected to be challenged in federal court and will be a dramatic shift in asylum policy. The restriction is the centerpiece of the Biden administration's attempt to blunt a potentially historic increase in the number of migrants crossing the U.S.-Mexico border when the Title 42 expulsions are discontinued at midnight on Thursday.
