The Immigration and Nationality Act (INA), enacted in 1952, reorganized immigration law and has been amended multiple times. It remains a key legal framework for U.S. immigration policies. The INA is part of the United States Code (U.S.C.), a compilation of federal laws, with Title 8 covering “Aliens and Nationality.” For accuracy, USCIS provides links to the official U.S. Code maintained by the Office of the Law Revision Counsel.
