The INA (Immigration and Nationality Act) is a federal law that governs the immigration policies and procedures of the United States. It is the primary source of immigration law in the United States and it is found in Title 8 of the United States Code.

The United States Code (USC) is the official compilation and codification of the general federal laws of the United States. It is divided into titles that represent broad areas subject to federal regulation. Each title is further divided into chapters, which contain the individual laws or statutes.

The INA is found within Title 8 of the United States Code, and it is the Title 8 of the USC that is the primary source of immigration law in the United States. The INA outlines the procedures for obtaining immigration benefits, such as visas, green cards, and citizenship. It also includes provisions for enforcing immigration laws, and for the removal of individuals who are in the United States illegally.
