The main purpose of this legislation, known as the Birthright Abuse and Nationality Act or the BAN Act, is to prohibit birth tourism in the United States. Birth tourism refers to the practice where foreign nationals travel to the U.S. primarily to give birth to a child, with the intention of that child obtaining U.S. citizenship. The Act aims to address concerns about the integrity of American citizenship and immigration laws, emphasizing that citizenship should not be treated as a commodity that can be bought or sold.
