The basics...
8am interview. Arrived 730am. Got through screening before 8am. Processing started at 8am. I was 9th in line on the IV. Took about 40 mins to get seen. Handed over required forms. Sat back down. 10am got my interview. Started smooth and smiley. Just basic questions about my fiance. All good until she asked if I have met her family. I haven't. Her mood changed. She said it was weird. I explained in detail why. A bit tense. Whole thing only 10-15 minutes of rapid questioning. And then she approved me. Easy!
I would recommend meeting the family! Ha. Apart from that no drama.
