EOIR is responsible for adjudicating immigration cases. Specifically, under delegated authority from the Attorney General, EOIR interprets and administers federal immigration laws by conducting immigration court proceedings, appellate reviews, and administrative hearings. EOIR consists of three components: the Office of the Chief Immigration Judge, which is responsible for managing the numerous immigration courts located throughout the United States where immigration judges adjudicate individual cases; the Board of Immigration Appeals, which primarily conducts appellate reviews of immigration judge decisions; and the Office of the Chief Administrative Hearing Officer, which adjudicates immigration-related employment cases. EOIR is committed to providing fair, expeditious, and uniform application of the nation's immigration laws in all cases.
