The Executive Office of Immigration Review (EOIR) is located within the US Department of Justice. It has administrative law judges who make the initial decisions.
Immigration Court decisions can be appealed to the Board of Immigration Appeals (BIA). The BIA generally issues non-precedent decisions. These apply existing law and policy to the facts of a given case. A non-precedent decision is binding on the parties involved in the case, but does not create or modify agency guidance or practice.
"Precedent decisions" are decisions selected and designated as precedent by the BIA.
Precedent decisions are legally binding on the DHS components responsible for enforcing immigration laws in all proceedings involving the same issue or issues. However, precedent decisions may be modified or overruled by:
The Attorney General
Later precedent decisions
Changes in the law
The BIA is not a federal court, but their decisions are subject to judicial review in the Federal courts. Federal courts give greater deference to precedent decisions as well as to unpublished decisions in which the same legal reasoning of a precedent decision was followed.
