Hello there, I'm a U.S. Citizen that just petitioned my brother (who is under 21) under Consular Processing. Considering that he was classified into the 4th Preference (based on the receipt notice) and that the Visa Bulletin for his country of birth (Mexico) indicates that the current priority dates are around year 1997, it seems that it'll be a looooong time until he is able to become a GC holder. I wonder if it's possible for me to petition my Mother to become a GC holder which should happen in around 1.5 years through Consular Processing and then after she is a GC holder upgrade my Brother's classification to F2A, for which the current visa dates are around year 2016, meaning a much shorter processing time from the current year (2 years apart). Does anyone know whether it is possible to just "upgrade" the classification or would we have to file a whole new petition for my brother but now with my Mom as the petitioner (and thus paying all the fees again)? Would anyone recommend doing this?, anyone mind sharing similar experiences? Thanks in advance!!
