I arrived for my 8AM appointment early and waited in line for a about an hour. Have to go into one line to confirm arrival and I was given a number and then another to go into the consulate. When I got in I went to sit down and wait for my number to be called. After 30 minutes I was called for a few preliminary questions with a very nice gentleman. Then I was told to sit again. I waited for about 2 hours this time I think, maybe less, and they skipped my number, which I was assured that this can be common. When finally called I was seeing a different gentleman this time. He asked me questions about me and my fiance, like what we did for a living, how long we'd known each other, when we were getting married ect. After about 5 or 10 minute he told me he'd approved my application and I was all done!
