I think it is really waste of time to really analyse how VSC is approving cases after FP2, because it just makes you really restless and you will be strained with the stress and it will slowly affect work and other things without knowledge.
So Friends, the best thing to do is try to find out whether all the security checks are done on your cases and they after a reasonable time after FP2, contact local representatives and then if nothing works, Just Pray GOD and I am sure it will work.
