I actually arrived really early as my appointment was at 12:30. I arrived at 10:30 via Paddington i went to the tent at 10:50 after visiting Starbucks. They were really nice and they let me go in early. When I got in there were lots of non immigrant visa people and I was sat there for about 30 minutes before being called. They called me to the door where they took my original documents and my fingerprints. They said to wait about 30 minutes for my interview I think it was about 40 then I was called. I had a really nice lady interviewer Who put my mind at ease. She asked me how I met my fiance and what we did for jobs. She also asked me what our wedding plans are. then she said your visa is approved I was so surprised as it was so simple. I am relieved and happy 2 have this first hurdle completed. Overall it was so much easier than I thought but I felt like where's my medal??? Lol. I guess i'll feel more triumphant when i get my visa!!
