The U.S. Citizenship and Immigration Services website describes Administrative Appeals Office decisions as such: "[t]he Administrative Appeals Office (AAO) generally issues our appellate decisions as non-precedent decisions, which apply existing law and policy to the facts of a given case. After review by the Attorney General, we may also issue precedent decisions to provide guidance to adjudicators and the public on the proper interpretation and administration of immigration law and policy. Additionally, USCIS may 'adopt' a non-precedent decision to provide policy guidance to USCIS employees in making determinations on applications and petitions for immigration benefits."
