(A)

an ambassador, public minister, or career diplomatic or consular officer who has been accredited by a foreign government, recognized de jure by the United States and who is accepted by the President or by the Secretary of State, and the members of the alien’s immediate family;
(ii)
upon a basis of reciprocity, other officials and employees who have been accredited by a foreign government recognized de jure by the United States, who are accepted by the Secretary of State, and the members of their immediate families; and
(iii)
upon a basis of reciprocity, attendants, servants, personal employees, and members of their immediate families, of the officials and employees who have a nonimmigrant status under (i) and (ii) above;
