U.S. Immigration Policy Program

Growing numbers of African and Asian migrants are moving through Latin America, many hoping to reach the United States or Canada after expensive, arduous, and often dangerous journeys that can take months or even years. As more extracontinental migrants transit through South and Central America, Colombia, Panama, and Costa Rica have developed the most comprehensive policies to manage these flows, sometimes working in coordination with the U.S. government.

Buoyed by initial successes challenging Trump administration immigration actions such as the travel ban in federal court, many critics expected the judiciary to act as a brake on major changes to the immigration system. Yet the Supreme Court has repeatedly shown a willingness to affirm the executive branch's immigration policies, most recently permitting what is arguably the most significant asylum policy change in four decades to proceed.
