Codification of Certain U.S. Citizenship and Immigration Services Law Enforcement Authorities
Document type: Rule Publication date: 2025-09-05 Document number: 2025-16978
Abstract
The Department of Homeland Security (DHS) is amending its regulations to codify certain law enforcement authorities delegated by the Secretary of Homeland Security (Secretary) to the Director of U.S. Citizenship and Immigration Services (USCIS) and subsequently redelegated to particular officers or employees of USCIS. These authorities allow particular USCIS personnel to investigate and enforce civil and criminal violations of the immigration laws within the jurisdiction of USCIS. These authorities include, but are not limited to, the issuance and execution of warrants, the arrest of individuals, and carrying of firearms.

Why this matters for immigrants
Federal Register publications under the Immigration topic tag have binding legal effect on:
- USCIS (immigration benefits, asylum, naturalization)
- ICE (enforcement, removal, detention)
- EOIR (immigration courts and the Board of Immigration Appeals)
- CBP (border admissibility and inspection)
Final Rules (“Rule” document type) become binding law on the effective date stated in the document. Proposed Rules are not yet binding and may be modified or withdrawn after public comment. Always verify the most current version of any rule at federalregister.gov before relying on it for legal or filing decisions.
