The Office of Inspector General (OIG) plays a critical role in helping the Department prevent and detect fraud, waste, abuse, and mismanagement. By doing so, the OIG helps improve the economy, effectiveness, and efficiency of DHS programs and activities. The OIG does this through independent and objective audits, investigations, evaluations, and inspections. It cannot do so alone. To carry out this important mission, the OIG needs certain information (for example, facts, reports, statistics, and data) from the Department and our Components.
