The Office of Immigration Litigation (OIL)

The Office of Immigration Litigation was founded in 1983 to watch over civil immigration litigation, including both affirmative and defensive cases. It is made up of two major sections, the Appellate section and the District Court section. It is responsible for the orderly presentation of nation immigration cases before the Federal District Courts and the Circuit court of Appeals.

In addition, OIL works with the United States Attorney’s Offices on immigration matters and supports and advises federal agencies regarding issues such as immigrant admission, regulation, and removal.
