The main purpose of this legislation, known as the "Ban Birth Tourism Act of 2026," is to prevent certain non-citizens from entering the United States with the intention of giving birth in order to secure U.S. citizenship for their children. This practice is often referred to as "birth tourism." The law aims to tighten immigration rules and discourage this specific pathway to citizenship. Key provisions of the law include new rules that classify non-citizens who come to the U.S. primarily to give birth as inadmissible.
