Tribal Border Crossing Parity Act

S 4558, the Tribal Border Crossing Parity Act, removes a blood quantum requirement for Indigenous people crossing U.S. borders. It amends immigration law to replace the "50% blood" standard with membership eligibility in federally recognized U.S. tribes or Canadian First Nations under the Indian Act. This change directly affects members or eligible members of these tribes/First Nations, allowing them to cross borders without proving specific blood quantum. The bill updates the legal definition to align with tribal sovereignty and membership status, not ancestry metrics.
