U.S. Immigration Policy Program
The U.S. Immigration Policy Program provides thought leadership on ways to improve the U.S. immigration system so that it works most effectively in the national interest. To that end, its work focuses on immigration pathways to the United States and immigration enforcement policies and their impacts. It examines the complex demographic, economic, social, political, foreign policy, and other forces that shape U.S. immigration.
Program staff produce data and analyses of immigration trends and the characteristics of U.S. immigrant populations, including unauthorized immigrants. And they conduct original research on the impacts of policy change and the experiences of immigrant populations in diverse parts of the country. This work is frequently informed by private convenings of policymakers and key stakeholders. For more, click here.
