Moreover, even when a respondent has a strong claim for relief a respondent has no guarantee that she or he will remain eligible or that a fact finder will grant her or his request for relief. See, e.g., Matter of Pineda, Int. Dec. 3325 (BIA 1997) (applying amendment to 212(h) to applicant who was eligible when request was filed); Matter of Yeung, Int. Dec. 3297 (BIA 1996) (applying amendment to 212(h) waiver to waiver applicant); Matter of Soriano, Int. Dec. 3289 (A.G. 1997) (applying amendment to 212(c) to applicant who was eligible when he first applied).
