US Embassies and Consulates are staffed with Foreign Service Officers who are responsible for visa processing. The Foreign Affairs Manual (“FAM”) and associated Handbooks (FAHs) are “a single, comprehensive, and authoritative source for the Department's organization structures, policies, and procedures that govern the operations of the State Department, the Foreign Service and, when applicable, other federal agencies.” The FAM contains general policy, whilst the FAH outlines procedures. In unison, the FAM and FAH provide codified information to officers and local staff to carry out their duties “in accordance with statutory, executive and Department mandates.”
