I had exactly the same experience just three days ago. After waiting in on the ACS side for 3 hours I asked a guard if I could go in to see if she was still there, because I thought she might have gone out already. He said it was okay as long as I didn't go to the interview. No problem. When I got to the other side she was almost to the window, so I just say down and waited. When it was her turn she came back 11 seconds later (I timed it), with denial. The VO didn't look at any of the supporting evidence (house in china, work contracts, visas, etc.) and when I asked her why, she simply said "You need to get a fiancee visa". I told the VO we didn't want a fiancee visa, we wanted a tourist visa, and her reply was a simple "she doesn't qualify". She offered no explanation beyond that. On that subject, if you go to the american citizen thing on mondays, can that officer issue a visa or is it just for information gathering and frustration enhancement? Anybody every get a visa this way after being denied?
