Border Security and Naturalization Enforcement Act of 2025

This Act provides funding to the Department of Homeland Security (DHS) for immigration enforcement activities strictly limited to the federal government's enumerated powers under Article I, Section 8, Clause 4 (naturalization) and Clause 3 (interstate and foreign commerce, including border security). Funding is authorized for U.S. Customs and Border Protection (CBP) and U.S. Immigration and Customs Enforcement (ICE) for the following purposes only: (1) personnel and technology at ports of entry and along the international borders of the United States to prevent unlawful entry and facilitate lawful trade and travel; (2) enforcement of federal immigration laws against individuals who have been convicted of violent crimes or who pose a threat to national security, as determined by a federal court; (3) removal of individuals who have been ordered removed by a federal immigration judge after due process proceedings consistent with the Fifth Amendment; and (4) administrative support for naturalization and asylum adjudications. No funds may be used for 287(g) agreements that delegate federal immigration enforcement to state or local law enforcement agencies, as such delegation raises Tenth Amendment concerns. No funds may be used for mass detention or removal of individuals without individualized judicial review. Funding is capped at $10 billion per fiscal year, sourced from a 5% surcharge on visa fees for non-immigrant work visas and a reduction in foreign aid spending by an equivalent amount. The Act sunsets after 5 years. Oversight is provided by the DHS Office of Inspector General, which must submit annual reports to Congress on compliance with constitutional limits. Enforcement is through private right of action for any individual harmed by a violation of this Act, with damages and injunctive relief available in federal court.
