MEXICO CITY—After the U.S. Supreme Court ruled Tuesday to keep pandemic-era border controls in place for now, thousands of migrants who amassed at the Mexico-U.S. border are weighing whether to wait or attempt to cross the border and enter the U.S. illegally. The migrants, many from Mexico and Central America but also from Venezuela and Cuba, and including many families, traveled to the border in recent days anticipating the end of Title 42 regulations, by which border crossers can be expelled immediately to Mexico or their countries of origin with no chance of requesting asylum. After the court’s ruling, the policy will now remain in place at least until February.
