This webinar, organized by MPI and the Zolberg Institute on Migration and Mobility at The New School, discussed the state of play around the globe surrounding COVID-19 and examined where migration management and enforcement tools may be useful and where they may be ill-suited to advancing public health goals. 

While migration once was a lower-priority topic for African governments, the last decade has seen a deepening in governance. Policymakers have integrated migration into their national development strategies and mainstreamed it across policy domains such as health and education. The actions are promising on paper, yet questions remain about the extent to which they will translate to more effective migration management.

MPI has released a major study that describes and analyzes today’s immigration enforcement programs, as they have developed and grown in the 25 years since IRCA launched the current enforcement era.

Release of a major report that describes and analyzes the immigration enforcement system in the United States as it has developed and grown in the quarter century since the Immigration Reform and Control Act of 1986 launched the current era of enforcement.

A timeline of key immigration laws and policy developments between 1986 and 2013.

This fact sheet compares key components of immigration reform outlined in the 2013 Senate immigration bill against provisions included in bills considered by the Senate in 2006 and 2007: border security, detention, and enforcement; worksite enforcement; visa reforms; earned legalization of unauthorized immigrants; strengthening the U.S. economy and workforce; and integration of new Americans.

MPI has completed an analysis of the major provisions in the 2013 framework, comparing them to provisions of the legislation the Senate considered in 2006 and 2007. 

This fact sheet is formatted as a chart comparing the framework of comprehensive immigration reform outlined in the 2013 Senate immigration bill against provisions included in bills considered by the Senate in 2006 and 2007.

The 10th annual Immigration Law and Policy Conference featured keynotes by U.S. Senator John McCain (R-AZ) and former Mississippi Governor Haley Barbour, as well as panel discussions covering a range of key immigration topics.

This report analyzes how governments ought to best allocate their resources to address the risks associated with migration—the "immigration harms" that undermine the positive economic and social benefits of immigration—including choosing which threats to tackle and where to prioritize enforcement efforts. Immigration policymakers can learn from other public policy regulation efforts to ensure that regulatory actions advance the public interest.

This Transatlantic Council on Migration Statement assesses the continuum of policies needed to disrupt illegal migration-related activities and addresses the conditions that make them possible.

Testimony of Marc Rosenblum before the Senate Committee on Homeland Security and Governmental Affairs for the March 26, 2015 hearing on the characteristics of unauthorized immigrants in the United States and how to address future flows.

An MPI Leadership Visions discussion with the Foreign Minister of Mexico, Claudia Ruiz-Massieu, for her first public appearance in Washington, DC. 

The Trump administration has released a list of hardline immigration demands—including border wall funding, restrictions on federal grants to “sanctuary” cities, and cuts to legal immigration—in exchange for legislation protecting DREAMers. This article examines the prospects for these proposals and more broadly for a legislative fix to resolve the status of unauthorized immigrants brought to the United States as children.

Looking back after one year in office, it is striking how just closely the Trump administration’s actions on immigration have hewed to priorities Donald Trump outlined in an uncommonly detailed policy speech in August 2016. This report revisits those pledges to assess where the administration has made the most and least headway, and what its policy agenda ahead might look like.

An unannounced sweep of 98 convenience stores by U.S. immigration authorities—resulting in the arrest of 21 unauthorized workers—may signal a new approach to worksite enforcement under the Trump administration, moving away from a strategy of paper-based audits that resulted in higher employer fines and fewer worker arrests. This article explores worksite enforcement over recent decades.

This provocative discussion showcases Charles Kamasaki's book, Immigration Reform: The Corpse That Will Not Die, and explores the lessons that can be learned from the Immigration Reform and Control Act of 1986, its intended and unintended consequences, and how the law’s legacy has shaped contemporary politics surrounding immigration.

This event marks the launch of a major new initiative—Rethinking U.S. Immigration Policy—that aims to generate a big-picture, evidence-driven vision of the role immigration can and should play in America’s future in order to leverage a comparative advantage for the nation.
