In the United States, Office of Inspector General (OIG) is a generic term for the oversight division of a federal or state agency aimed at preventing inefficient or unlawful operations within their parent agency. Such offices are attached to many federal executive departments, independent federal agencies, as well as state and local governments. Each office includes an inspector general (or I.G.) and employees charged with identifying, auditing, and investigating fraud, waste, abuse, embezzlement and mismanagement of any kind within the executive department.
