(h) RULES FOR DETERMINING WHETHER CERTAIN ALIENS ARE CHILDREN-
(1) IN GENERAL.-- For purposes of subsections (a)(2)(A) and (d), a determination of whether an alien satisfies the age requirement in the matter preceding subparagraph (A) of section 101(b)(1) shall be made using--
(A) the age of the alien on the date on which an immigrant visa number becomes available for such alien (or, in the case of subsection (d), the date on which an immigrant visa number became available for the alien's parent), but only if the alien has sought to acquire the status of an alien lawfully admitted for permanent residence within one year of such availability; reduced by
(B) the number of days in the period during which the applicable petition described in paragraph (2) was pending.
(2) PETITIONS DESCRIBED- The petition described in this paragraph is—
(A) with respect to a relationship described in subsection (a)(2)(A), a petition filed under section 204 for classification of an alien child under subsection (a)(2)(A); or
(B) with respect to an alien child who is a derivative beneficiary under subsection (d), a petition filed under section 204 for classification of the alien's parent under subsection (a), (b), or (c).
(3) RETENTION OF PRIORITY DATE- If the age of an alien is determined under paragraph (1) to be 21 years of age or older for the purposes of subsections (a)(2)(A) and (d), the alien's petition shall automatically be converted to the appropriate category and the alien shall retain the original priority date issued upon receipt of the original petition.
(4) APPLICATION TO SELF-PETITIONS- Paragraphs (1) through (3) shall apply to self-petitioners and derivatives of self-petitioners.
The Second Circuit in Li went a step further, holding that the statutory language was not even ambiguous, and that one need not resort to legislative intent to find that a priority date could not be retained “to use for a different family petition filed by a different petitioner.” Under circumstances such as the grandfather/child/grandchild fact pattern noted earlier (modeled on the facts of Li), the Second Circuit said, there is no “appropriate category” to convert to, because there is, for example, “no family preference category for grandchildren of LPRs”.
