In a report released in July, the Migration Policy Institute offers a comprehensive catalog, by topic, of changes made by the Trump administration to the U.S. immigration system since entering office in January 2017.
The report, “Dismantling and Reconstructing the U.S. Immigration System: A Catalog of Changes under the Trump Presidency,” was written by Sarah Pierce, a Policy Analyst for the U.S. Immigration Policy Program at MPI, and Jessica Bolter, an Associate Policy Analyst with the U.S. Immigration Policy Program at MPI.
