I emailed in advanced to ask if I could attend my fiance interview, they said I could enter but then when we arrived they would not let me in. Aside from that everything was okay. Visa approved, they were polite (says my fiance) and efficient. This Embassy has greatly improved over the last year, it's now only one interview not two and things are a lot smoother. Make sure to EMAIL for packet 3/4 if you wait for the mail you will never have an interview, also just schedule the interview online.
