petition for unmarried children

[cocon0304]

My parents, who are legal permanent residents (LPR), are going to sponsor for my siblings to the US. Is my sister qualified as "unmarried child" if her 21st birthday comes before the filing date of I-130 or the Priority date? In other words, before what day her 21st birthday must be for her to be considered as "unmarried child", not as "unmarried daughter"? What is the waiting time difference in these two categories? If my sister is considered as unmarried daughter when my parents petition, would it be faster if I, a US citizen, petition her following siblings petition?

Another question is for my little brother's case. He's only 8 years old now. When my parents apply i130 for him, will the process go faster due to his young age? What is the estimate waiting time for his case?

thank you =)

The older sister would likely NOT benefit from CSPA so she would likely convert from F2A to F2B anyway. The 8 y/o will be F2A and stay that way as it will not take so long as to be an issue of aging out and converting like the almost 21 y/o.

If Mexican, the USC sibling should file for the almost 21 y/o sister as the F2B takes longer. Even though right now this situation ONLY happens for Mexicans, who knows what will happen in the future? I would suggest everyone do it BOTH ways (F2 by LPR parents and F4 by USC siblings) as a back-up plan.
