Nationality is the legal relationship between a person and a state. The person becomes subject to the state's laws, even while not physically present in the state, in exchange for the state's protection, and other rights.
The Immigration and Nationality Act of 1952, (INA) with some major, and many minor changes, continues to be the basic immigration law of the country. The most significant amendment to the INA was in 1965, which abolished the natural origin provisions and established a new quota system.
