1952 – McCarran-Walter Immigration Act Organizes All Immigration Statutes into One Body of Law

“The Immigration and Nationality Act,
or INA, was created in 1952. Before the INA, a variety of statutes
governed immigration law but were not organized in one location. The
McCarran-Walter bill of 1952… collected and codified many existing

been amended many times over the years, but is still the basic body of
immigration law. The INA is divided into titles, chapters, and sections.

the United States Code (U.S.C.).”
