The Birthright Citizenship Act of 2025 aims to clarify who is considered a citizen or national of the United States at birth. The main objective is to define the classes of individuals born in the U.S. that automatically receive citizenship under the law. Key provisions of the Act include a clear definition of who qualifies for citizenship at birth. It states that a person born in the U.S. is considered "subject to the jurisdiction" of the U.S. if at least one parent is either a U.S. citizen, a lawful permanent resident, or an alien with lawful status who is serving in the military.
