In the past 15 years, TRAC has become a valuable source of immigration data for journalists, researchers, policy makers, and the general public. This report provides a brief introduction to our immigration data so that you can better understand how TRAC works, what data we have, and how to use our tools.
TRAC's data is obtained from federal agencies through Freedom of Information Act (FOIA) requests as well as directly from the federal courts. Rather than requesting documents through FOIA, TRAC requests data from the government's own internal databases, which provide insight into what federal agencies are actually doing on a day-to-day basis-including key immigration enforcement agencies.
In the full report, we summarize the role that each of the following agencies play in the US immigration system: Immigration and Customs Enforcement (ICE), Customs and Border Protection (CBP), and the agency responsible for managing the Immigration Courts (the Executive Office for Immigration Review, or EOIR). We also explain the basics of how deportation works, including arrested, detention, the removal proceedings process, and deportation. Equipped with this understanding, you can more easily identify which of TRAC's immigration data tools fits your needs.
