NOGALES, Mexico (AP) — The Biden administration’s asylum halt that has led to a 40% drop in arrests for illegal border crossings this month falls hardest on nationalities most susceptible to being deported. The asylum halt applies that took effect June 5 to all nationalities. But Mexicans and those Mexico agrees to take back are most likely to be deported. That includes Cubans, Haitians, Nicaraguans and Venezuelans. Lack of money for charter flights, sour diplomatic ties and other operational challenges make it more difficult to deport people to many countries in Africa, Asia, Europe and South America. Homeland Security Secretary Alejandro Mayorkas says the U.S. is working with countries around the world to accept more of their deported citizens.
