I just had my interview done at Garden City today. Hope my experience can help you a little. When I went to the IO's office, he asked me for my GC and my passport; then he did ask me to sign my 2 photos. I certainly signed off a lot of papers. After all the questions and English tests; the IO congrad me for the approval of the application, and gave me a paper stating that my application is recommended for approval. The OL will mailed to me later.
