Your Visa is approved, you may pick up your passport/visa after 1 week.
(totally did not expect that, I was surprised)

I was really nervous as the two other applicants before me were denied by the consul who interviewed me (the other one has same purpose as me, but she's married and has travelled to one country only). I've answered all questions as honest as possible with short answers and also dressed appropriately to make good impression. I wasn't asked to show any supporting documents, just handed over my passport.

Just picked up my Visa today and learned that I got 10 years/Multiple entry. I think being able to travel in the past to several countries helped.
