Full Text
An unsuccessful petitioner may re-petition only if AS-IA determines that the petitioner has plausibly alleged one or both of the following:
(a) A change from part 54 of this chapter (as it existed before March 30, 1982) or part 83 (as it existed before July 31, 2015) to this part 83 would, if applied on reconsideration, change the outcome of the previous, negative final determination to positive; and/or
(b) New evidence (i.e., evidence not previously submitted by the petitioner) would, if considered on reconsideration, change the outcome of the previous, negative final determination to positive.
