The Ban Birth Tourism Act would make it illegal for foreign visitors to enter the United States if their primary purpose is to give birth and obtain U.S. citizenship for their child. The bill amends immigration law to classify such individuals as inadmissible at the border, effectively preventing them from traveling to the country for this reason. The legislation would affect pregnant foreign nationals seeking to travel to the U.S. on visitor visas, though it includes a narrow exception for those genuinely seeking medical treatment for childbirth-related complications where citizenship is not the main goal. The bill does not include any funding or implementation timeline, and it was referred to the Senate Judiciary Committee in May 2025.
