Birthright Citizenship Act of 2025

S 304, the Birthright Citizenship Act of 2025, would amend U.S. immigration law to redefine who qualifies for automatic U.S. citizenship at birth under the 14th Amendment. It specifies that a child born in the U.S. gains citizenship only if one parent is a U.S. citizen, a lawful permanent resident living in the U.S., or a military service member in active duty. This change would exclude children born to undocumented immigrants from automatic birthright citizenship under this definition. The bill explicitly states it would not affect citizenship status for anyone born before its enactment date. The legislation focuses on clarifying the "subject to the jurisdiction" requirement in existing law, not creating new citizenship categories.
