The Biden administration is expanding the areas in southern Mexico where migrants can schedule online appointments via the CBP One app to include the states of Chiapas and Tabasco. This initiative, aimed at easing pressure on the Mexican government and increasing migrant safety, responds to a request from Mexico and is part of ongoing collaborative efforts to manage migration flows. By allowing appointments to be secured without traveling north, the change is expected to reduce risks for migrants. U.S. officials noted that increased enforcement by Mexico has significantly lowered unauthorized border crossings in the first half of the year. This expansion comes after the U.S. temporarily halted asylum processing for unauthorized entries, making CBP One one of the few options for seeking asylum. Overall, the measures reflect a notable decrease in migration since late last year, as stated by Mexico's Foreign Affairs Secretary.
