I was only asked about DS160, Birth Certificate, pictures, police certificate and affidavid.
Mrs. consul was very nice! She was kind and was smiling all the time, so all stress was gone.
For the interview I was waiting about 2,5 hour. Conversation took about 5-10 minutes.
She apoligized me that I had to wait so long (I was last in the line). Then I swear that everything I say is true and she started to ask questions like: How did we meet? How many times my fiance visited me? Did I see his parents? What my parents say about all this situation? Do I have siblings? What is common in me and my fiance? What do we like to do together? What I am going to do when I arrive to the states? What kind of studies? When I am going to depart? How and when we plan our weeding? etc.
Converstaion was easy and without stress.
Ah, and she wanted to see our pictures and some of them I described. She also knew what time each one could be taken, what shows that she knows our case very well.
And the end "that's all" and she informed me when I can pick up my passport.
