Thank you so much Shankar for this guidance. I called CIC yesterday and they suggested to respond to the email with the documents you have along with the explanation letter. Just like you said.I was in a similar situation as you and i gave them the following:
Garde 10, aadhar card, voter ID, expired Indian passport, PAN card, OCI
They were happy with it I assume since my application has reached the final approval stage.
I submitted 13 additional documents and explanation letter to satisfy them a couple of hours back.
One more thing I wanted to say is that I've received the AOR email also on 8 May with that default language that if not already included submit the Financial Evaluation form. But since I included it in the application itself, I am not resending it.
Please suggest if it is the right approach.
Other question I have is how come I received the AOR on 8th May, if they requested for additional documents on 11 April?
