In applying this section to a special immigrant described in section 1101(a)(27)(J) of this title-

(1) such an immigrant shall be deemed, for purposes of subsection (a), to have been paroled into the United States; and

(2) in determining the alien’s admissibility as an immigrant-

(A) paragraphs (4), (5)(A), (6)(A), (6)(C), (6)(D), (7)(A), and (9)(B) of section 1182(a) of this title shall not apply; and

(B) the Attorney General may waive other paragraphs of section 1182(a) of this title (other than paragraphs (2)(A), (2)(B), (2)(C) (except for so much of such paragraph as related to a single offense of simple possession of 30 grams or less of marijuana), (3)(A), (3)(B), (3)(C), and (3)(E)) in the case of individual aliens for humanitarian purposes, family unity, or when it is otherwise in the public interest.

The relationship between an alien and the alien’s natural parents or prior adoptive parents shall not be considered a factor in making a waiver under paragraph (2)(B). Nothing in this subsection or section 1101(a)(27)(J) of this title shall be construed as authorizing an alien to apply for admission or be admitted to the United States in order to obtain special immigrant status described in such section.
