Everything was pretty straight forward. I actually flew in and (plus have fun) attended the interview with my fiance. I will not repeat the whole entering and waiting process, as its been said multple times.
At the first window I was asked where I worked. I answered and stood with him. When he was called for the actual interview the CO just asked me how we met and then said I could sit down it shouldn't take long. I could hear some of the questionstreet being asked nerves aside the questions were pretty straight forward and not out of the ordinary.
Visa approved!
As a side note I did meet an awesome young lady while he was interviewing.
One suggestion I would make for the process over all is, Transparency. Lots of it. These decisions and processes tell d to affect more than one person's life. Our life was hanging in the balance and to have no status updates or correct updates is nerve racking and unnecessary. Your basically blind and dependent on bureaucracy.
