Bro you good. Kind of overkill LOL. I submitted basically the same evidence as you. If you show up with your fiance for the interview, it's practically a lock going by what you have said.
During the super short interview, they asked my fiance one question...what was my job. I don't even think they asked me anything at all.
Also, they "interviewed" my fiance alone...I was told to have a seat nearby in the waiting area in front of the booths. After like a min she gave me a thumbs up and I went up to the booth and said thanks and we left.
