The entire interview process was over in less than 30 minutes. I arrived at the embassy at 10.15 for my 11.00 appointment and they let me straight through. Passed through security and through to the first desk within issues. The directions given were simple and i went to the immigrant interview section with no issue. There was just one other applicant there when I arrived. At the first window i handed the requested documents. I had way more than required, but that was mainly for my own piece of mind. I was approved at the second window after three or four questions! I was out by 10.45. Everyone i spoke to inside and outside of the embassy was lovely.
