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.

The Public-Charge Rule: Broad Impacts, But Few Will Be Denied Green Cards Based on Actual Benefits Use
While the Trump administration public-charge rule is likely to vastly reshape legal immigration based on its test to assess if a person might ever use public benefits in the future, the universe of noncitizens who could be denied a green card based on current benefits use is quite small. That's because very few benefit programs are open to noncitizens who do not hold a green card. This commentary offers estimates of who might be affected.
Coronavirus Is Spreading across Borders, But It Is Not a Migration Problem
Travel bans, border closures, and other migration management tools did not prove effective at blocking COVID-19 from spreading across international borders. Yet as governments have shifted from containment to mitigation with the coronavirus now in community transmission in many countries, these restrictions are a logical part of the policy toolkit in the context of social distancing and restricting all forms of human movement, as this commentary explores.

USCIS Fee Increase Proposed Rule Could Represent the Latest Step in Reshaping Immigration to United States
While much attention has been given to the move by U.S. Citizenship and Immigration Services to raise its application fees—including an 83 percent hike to apply for U.S. citizenship—the policy changes embedded in the proposed rule have been less scrutinized. The changes, including the elimination of most fee waivers for lower-income applicants, would likely reduce the number and shift the profile of those getting a green card or other immigration status.
