This legislation, titled the Department of Homeland Security Appropriations Act, 2026, provides appropriations for the Department of Homeland Security (DHS) for the fiscal year ending September 30, 2026. It is divided into two main parts: Division A, which details the DHS appropriations, and Division B, which addresses further additional continuing appropriations for 2026. The bill references an explanatory statement for specific fund allocations and implementation details, ensuring transparency and accountability in spending. Funding is allocated across various departmental components, beginning with Departmental Management, Intelligence, Situational Awareness, and Oversight . This includes significant amounts for the Office of the Secretary and Executive Management, the Management Directorate, and the Office of Intelligence and Analysis. The Office of Inspector General receives substantial funds, with specific allocations for additional inspections and oversight of detention facilities, as well as oversight of funds from prior public laws. Under Security, Enforcement, and Investigations , major appropriations are made for U.S. Customs and Border Protection (CBP) and U.S. Immigration and Customs Enforcement (ICE). CBP receives funds for operations, including transportation of unaccompanied alien minors and air/marine support, alongside procurement for border security assets. ICE's budget supports operations, including Homeland Security Investigations with dedicated funding for combating forced child labor and intellectual property rights violations, and Enforcement and Removal Operations. Further allocations in this division cover the Transportation Security Administration (TSA), the Coast Guard, and the United States Secret Service. TSA's budget focuses on operations, procurement for security equipment, and research and development. The Coast Guard receives substantial funding for operations, procurement of vessels and aircraft, research, and retired pay. The Secret Service is funded for protective functions, investigations, and specific grants for missing and exploited children, with provisions addressing overtime compensation and protective service demands. The Protection, Preparedness, Response, and Recovery division funds the Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Emergency Management Agency (FEMA). CISA's budget supports operations and procurement for cybersecurity and infrastructure protection. FEMA receives extensive federal assistance grants, including for State Homeland Security, Urban Area Security, Nonprofit Security, Port Security, Assistance to Firefighter (AFG), and Staffing for Adequate Fire and Emergency Response (SAFER) programs. Significant amounts are also provided for the Disaster Relief Fund and the National Flood Insurance Fund . The Research, Development, Training, and Services division provides funds for U.S. Citizenship and Immigration Services (USCIS), Federal Law Enforcement Training Centers (FLETC), and the Science and Technology Directorate. USCIS receives additional funds for operations, including the E-Verify Program. FLETC is funded for operations, procurement, and construction of training facilities. The Science and Technology Directorate's budget supports operations, procurement, and research and development initiatives. General provisions outline rules for fund transfers, reprogramming limitations, and reporting requirements to Congress. Key administrative directives include: restrictions on border crossing fees; conditions for detention service contracts; prohibitions on certain surveillance systems; requirements for pilot program documentation; limitations on intelligence activities; and mandates for monthly migrant arrival and detention estimates. The bill also rescinds unobligated balances from various prior appropriations accounts across DHS components, and Division B ratifies obligations incurred during a lapse in appropriations, ensuring continuity of essential government functions.
