The U.S. immigration court system is organized into a hierarchy with three primary levels. The first level consists of the Immigration Courts, where immigration judges preside over removal proceedings and make decisions on various immigration matters. Should you not agree with the ruling of an Immigration Court, you can appeal the decision to the Board of Immigration Appeals (BIA) at the next level. The BIA conducts a review of Immigration Court decisions and either affirms or reverses the ruling. Lastly, if you disagree with the BIA's decision, you can appeal to the U.S. federal appellate courts, which mark the final level of the hierarchy.
