Im not doing the F2A visa from India but when we submitted final documents to NVC in November, we were told it could take up to 6 weeks to process them. It took 10 we called at the 6 week mark and no one had looked at our paperwork yet. They submitted it to a supervisor. I then called every week to see if there was progress. Finally 4 weeks after the 6 week mark we were approved. It then took another 3 weeks for an interview date to be scheduled.
