U.S. Strategy for Engagement in Central America: Policy Issues for Congress [Updated June 12, 2019] [open pdf - 1MB]
From the Document: "Central America has received renewed attention from U.S. policymakers over the past few years as the region has remained a major transit corridor for illicit drugs and has surpassed Mexico as the largest source of irregular migration to the United States. These narcotics and migrant flows are the latest symptoms of deep-rooted challenges in several countries in the region, including widespread insecurity, fragile political and judicial systems, and high levels of poverty and unemployment. The U.S. government and partners in the region have begun to implement new initiatives intended to address those challenges, but living conditions in Central America have yet to improve significantly."
