## What this funds

The Operations and Support (O&S) appropriation funds the Office of Inspector General's (OIG) independent and objective audits, inspections, evaluations, and investigations of the Department of Homeland Security's (DHS) programs and operations. DHS OIG was established through the Homeland Security Act of 2002 by amendment to the Inspector General Act of 1978 and serves the Department and its Secretary, the President, the Congress, and the public. DHS OIG makes independent and objective recommendations to improve the efficiency and effectiveness of DHS's programs and operations. Our robust oversight helps the Department fulfill its vital mission to secure our Nation and safeguard its people. Annually, DHS OIG receives thousands of complaints, issues dozens of audits, inspections, and evaluation reports, and conducts hundreds of investigations. DHS OIG produces impartial, timely information about the performance of DHS programs and operations, and objectively assesses emerging issues. Our recommendations are designed to promote good governance, informed decision making, transparency, and accountability across the Department. DHS OIG strategically initiates audits, investigations, and inspections that are data-driven and risk-based to maximize our impact within our limited resources. We align our work with DHS's six critical mission areas: 1) Counter Terrorism and Prevent Threats; 2) Secure and Manage Our Borders; 3) Administer the Nation's Immigration System; 4) Secure Cyberspace and Critical Infrastructure; 5) Build a Resilient Nation and Respond to Incidents; and 6) Combat Crimes of Exploitation and Protect Victims. We conduct legislatively mandated work and other high-value, discretionary reviews to address Departmental risks. Our findings are reported to the DHS Secretary, the Congress, and the public, consistent with the law. Additional information about our work may be found at www.oig.dhs.gov.
