The main purpose of this legislative proposal is to amend the U.S. Constitution to clarify that the 14th Amendment does not automatically grant citizenship to children born in the United States to parents who are not U.S. citizens or lawful permanent residents. This change aims to specifically define who is considered "subject to the jurisdiction of the United States," which is a key phrase in the 14th Amendment regarding citizenship. The key provisions of this proposal include a new definition of who qualifies for citizenship at birth.
