Me and my wife currently living in USA. I am on H1B and my wife is permanent resident. She filed family based GC for me under F2A category in Aug 2011. In june 2012 i got I-130 approved. But the NVC case number is BMBXXXXXXXXXX and in online i found BMB stands for Mumbai consulate , does that mean i will get visa interview in Mumbai when my visa number is available. If yes how it works, i live and work in USA legally and how can they assign me BMB number. Can some one please clarify. Let me know if needed more information.
Thanks in Advance.
