Yes, I'm the sponsor and the representative.That is correct.
I am assuming you are the sponsor and also your wife's representative and that is why you got the additional document requests and PassPort Request for your wife. So these recent emails had your name spelled incorrectly - must be a human error. You can probably call them up and let them know what is going on. However, not very confident if that is what you should do, so may be wait for some more experienced members in this forum to share their opinions?
Thank you! I'll wait for more inputs from other members.
