Getting My Visa

So I had to go to Chicago for my visa. I flew there a few days ago and walked there from my hotel. When I was sitting and waiting a bunch of girls in front of me started asking me why I was here and I told them the whole story "AFS.." And then I asked them what they were doing here and all 4 of them said they were going to teach English! That is what I would like to do when I am older! So we talked while we all waited for the family that didnt have their paperwork! Short and simple. To be honest, I didnt fully understand why it had to be and in-person-appointment because the whole thing was talking to a man behind glass. He didn't even look at me! Oh and he only needed like half the paper work we were supposed to bring. Right now, I am super relieved that I know I will get my visa!
