In my humble opinion, I think that you should not waste your money mailing it again, since you scanned it Initially.If I were you to satisfy the curiosity of my mind, I would resend the scanned copy with a short and brief note after your information. My email will be a follow up one. Dear officer what ever the initial is, please acknowledge my attached scanned requested copy, please advise if this is accepted by your standard or should I still mail it. I bet you that all she/he will do is to respond by saying that is all good and that you will hear from us shortly. I emailed them regarding my posted mail to Accra, they just got back to me today after 6 days. Macus, remember my time prediction of month end,You are so so close and your visa is ready or nearly ready as we speak.
