I hadn't heard anything after about half a day and so I decided to call the consulate to see if I could find the answers to these last questions prior to mailing out my application today.
Belgium is a small place. The consulate is even smaller. I know this because the woman who first answered the phone happened to be the VISA OFFICER. I'm so used to getting a secretary or something, I didn't even think as I asked to be referred to the visa officer that I was already speaking with her. The woman on the other end sounded a tad annoyed: "yes, I responded to your email this morning... Jessica, yes?" I said "yes" and apologized saying I hadn't yet received the mail and explained I'd thought to call in case my email was being slow to deliver. The woman reiterated she'd sent it at 11-something this morning, and then proceeded to tell me "as I said in the email..." explaining to me that sending my real passport would help to speed things up because a copy is only sufficient to start the process, but in the end they'd need my real passport to put the visa sticker in if my request is approved.
I thanked her, trying to sound as grateful as possible for taking the trouble to answer me, (twice,) and upon hanging up the phone realized that I may have annoyed, or seemed like a complete tool to the person who will be processing my visa request.
