one thing i have observed is that all these concurrent approvals octfiler, cocktail and nandu are all eb3 cases, i wonder whats up with that. they havent got to eb2 as yet looks like. or is it a just a coincidence, with NSC i would expect it to be more of a coincidence than a pattern i guess , keeping it in line with their random fashion. i am eb2 and waiting to see some action on concurrent approvals for the eb2 category.
congrats octfiler, i did post a message in the other forum congratulating you. all the best for the future.
