Reports
July 2020

Now into its fourth year, the Trump administration has reshaped the U.S. immigration system in ways big and small via presidential proclamations, policy guidance, and regulatory change. This report offers a catalog of the more than 400 administrative changes undertaken in areas such as immigration enforcement, humanitarian admissions, DACA, and visa processing—including a look at measures put in places since the onset of the COVID-19 pandemic.

May 2019

In the two years since President Trump entered office, U.S. immigration policy has changed in many ways. Some actions have received significant media attention and public scrutiny, and others have been implemented with little fanfare. This document chronicles these wide-reaching policy changes, covering immigration enforcement, the immigration courts, humanitarian admissions, visa processing, and more.

This policy brief traces the successes and failures of the 1986 Immigration Reform and Control Act, which represented the first and most comprehensive legislation to take on the issue of illegal immigration to the United States.
