Thank you ascetic.
The process of applying here is all the same like everyone else's (I think). During the interview proper, if the consul returned your passport after talking, you are denied because they can't process your passport because they're returning the passport back to you plus a blue paper of I don't know what does it says.
However, if the consul gave you a yellow slip of paper and the passport was not returned to you, then you made it. They keep your passport for visa processing, and so the yellow slip is just a courier slip the courier service requires for so they cand eliveer your visa right at your doorstep.
I have been approved for visa. The consul gave me a yellow paper in which I gave it to the courier services for the delivery of my passport after 4 working days of visa processing.
I am from the Philippines. I applied at Manila US Embassy. I am now looking forward to have my graduate studies in the Univ. of Kansas majoring in Chemistry PhD.
I forgot the details of the interview, it was short though. The talk was mostly about who will finance my studies there. In the long run, I had a great time talking with the consul. We were laughing after all.
