The Immigration and Nationality Act of 1952 (INA)

One of the most important federal statutes governing immigration law is the Immigration and Nationality Act (INA). The INA was initially signed into law in 1952, and has been amended many times since then. The INA is codified at Title 8, U.S.C., §§ 1101-1537. Statutory provisions can be cited as sections of the INA or as United States Code sections. For example INA §247 is the same section as 8 U.S.C. § 1257.
