Thousands of migrants have fled Cuba ahead of the potential change in the special humanitarian provision of a U.S. law, the Cuban Adjustment Act. They flooded the small town of La Cruz, Costa Rica after the Nicaraguan government closed its border to all illegal immigration on Nov. 13, 2015. Most of the migrants have been been there for months and will be airlifted north to El Salvador with a final destination of the United States. Many government shelters have reached their capacity and new Cuban arrivals have resorted to sleeping in the streets and other public areas.
