I am sorry to bother you with this questions, but, F-2A should be applied separately? (There is a section named "Additional Information" which is one of the lasts steps before submitting the form I-130 online). And by sources you mean alll the information you guys have shared with me? Like for example this:
B. When a New Petition May Be Required to Recapture a Priority Date
Based on the language of the DHS regulations, as well as dicta in the Supreme Court decision in Cuellar de Osorio,22 there is a reasonable argument that derivative beneficiary children of LPRs who naturalize, automatically convert to immediate relative beneficiaries, without a new petition being filed by their newly naturalized parent. It is clear that the BIA in Matter of Wang overruled one regulation which required a new petition for aged out derivatives moving from the F2A to the F2B category.
