This research guide provides an overview of pertinent resources for the Immigrant Advocacy Concentration at Loyola Law School and immigration law practice generally.

About Federal Statutes

What Are Federal Statutes?

Federal statutes are laws enacted by Congress.

How Are Federal Statutes Published?

Federal statutes are first published as individual acts (also called public laws or slip laws). Later, they are organized by date in the Statutes at Large (Stat.) and then by subject area in the United States Code (USC.) 

Where Are Immigration Statutes Located?

Most immigration statutes are part of the Immigration and Nationality Act (INA), located within Title 8 (Aliens and Nationality) of the USC at 8 U.S.C. §§ 1101-1178. For example, INA § 212 (The 212th section of the Immigration and Nationality Act) is located at 8 U.S.C. § 1192 (The 1192nd section of Title 8 of the United States Code.)

United States Code Online and in Print

The U.S. Government Publishing Office publishes the official United States Code (USC), Lexis publishes its own unofficial United States Code Service (USCS), and Westlaw publishes its own unofficial United States Code Annotated (USCA.)

The text of all three versions is almost always the same but both Lexis and Westlaw each add their own unique annotations- links to relevant cases, regulations, and secondary sources, located at the end of the statute on Lexis and in print and under the Notes of Decision and Context & Analysis tabs on Westlaw.

Rains Library provides access to all three versions in multiple formats:
