Title 42 expiration brings uncertainty and chaos to U.S.-Mexico border.

The Biden administration has finalized a new restriction on asylum that will disqualify migrants from U.S. protection if they fail to request refugee status in another country, such as Mexico, on their journey to the southern border. The regulation will be used to ramp up swift deportations of migrants who cross the U.S.-Mexico border after the Title 42 pandemic-era emergency policy sunsets on Thursday. 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.
