USA Immigration Laws

USA Immigration Laws

United States immigration laws are covered under the U.S. Citizen and Immigration Services (USCIS). The USCIS in turn is one of the many federal government components that fall under the Department of Homeland Security (DHS).

The law section of USCIS deals with the regulations and interpretations of USA immigration laws, while the DHS, in turn, is responsible for investigating and enforcing the US immigration laws, as well as the customs laws, and air security laws.

USA Immigration Laws

The basis of U.S. immigration law is the Immigration and Nationality Act (INA) which came into being in 1952. This Act can also be found in the United States Code (U.S.C.) which is the collection of all United States laws. To view the 51 titles of U.S. Code visit Cornell University Law School.

Since 1952 the INA has undergone multiple public law amendments over the years. Amendments are first published in the Federal Register, then again listed in the Code of Federal Regulations (CFR). The CFR is mirrored on the United States Code (U.S.C.), and as such, you will find that both Title 8 of the CFR, and Title 8 of the U.S. Code covers “Aliens and Nationality”.
