Petitioned for parents green card, but their aging child is not able to come with them based on I-130 rules.
I am a US citizen and petitioned for my parents’ and sister green cards a year ago. My parents recently got their immigrant visas and are coming to the US. But my sister who is 19 years old was not able to come with them because immediate relatives are not eligible to come with them. Can it be possible for them to petition for my sister here in the US. Does she still have time before she turns 21 to qualify as a child on F2A category? I am worried about this. I made calculations and I believe she is just in time or even miss the availability of a visa by a month according to the current Visa bulletin.
