Hi
@mianusama723, if you go to the ceac status check (please google it as I can't put the link here) and enter your case number, how many enteries do yo see? So, for example, if we assume you have 2 younger siblings and you mentioned that you and your sister are 27 and 25, do you see 4 enteries or do you see 6 enteries (including parents)? The reason for my question is to determine whether the consulate had already decided your (and your sister's) disqualification before you went in on interview day or after you went in.
Also, I found your CSPA age to be 24 years 9 months and 22 days; and so any of your siblings that qualified had to be born on or after October 12th, 2000. Being born on or before Oct 11th 2000 disqualifies in your case.
Unfortunately, the Department of State doesn't go by the USCIS policy manual, they have their own, namely: the foreign affairs manual, and until that normalizes the legal language with USCIS, CSPA will be calculated by the old formula.
Please do check the case status and let us know how many enteries you see and what it says next to each (Issued, Refused....)...it would be interesting to know because certainly the NVC included you in the interview letter and should have had your enteries there (yours and yours sisters).
