Once the State Department makes a determination that a person is an "alien who, while serving as a foreign government official, was responsible for or directly carried out, at any time, particularly severe violations of religious freedom, as defined in section 6402 of title 22," the person becomes inadmissible to the United States (8 USC § 1182(a)(2)(G)).
(This is subject to exceptions while such person might happen to benefit from a diplomatic visa; I also understand there is also a path for the Secretary of Homeland Security to issue a waiver.)
My question is: separate from the exceptions just listed, may the State Department make a redetermination under 8 USC § 1182(a)(2)(G), or is the State Department forever bound to the conclusion of its initial determination of inadmissibility? If a redetermination is possible, are there procedural prerequisites? (E.g. must there be an application? Must there be fresh evidence?)
