My Fiance went to embassy by herself at 7 am, she got her fingerprints done, submitted the fees, PCC and I134.
During the interview they only asked her for her name, my name, how we met, why are we getting married in us (because of my work) and what kind of work i do, and then she was told her visa is approved and she was out around 9:30 am.
They did not even ask for any of the proof or any other paper work.
