Everything went smooth and easy 🙂 I had appointment scheduled at 10.00, had to wait about 2 hours for my final interview. It seems like embassy scheduled all appointments for the same hour (about 20 ppl was waiting with me). Interview was quick with typical questions like "How did you meet your fiance?" "What's he doing?" "How long do you know each other?". After 3-4 days I had my passport back with visa and documents.
