For some reason, this and your entire post ended up giving me the warm fuzzies. You two seem really happy together, and it shows. fuzzies
FWIW, here are some sample questions if you want to see how you would do on the long interview.
I went through the process with my wife and they didn’t ask us any of the movie-type interview questions at all, just the sort of stuff anyone might ask while making small-talk, and we were never separated during the interview. All our paperwork was in order, we had joint everything. We also had a good-sized wedding ceremony where most of my extended family flew in from across the county, so it was pretty clearly real. We were there maybe 10 minutes, tops. From what I understand, they don’t go into the long interview stuff unless there’s red flags that make them suspect fraud.
