Having successfully gone through the process and getting the dreaded window seven guy with no problems, let me say this. I think it is good to be paranoid and over-prepared. But, after reading many posts and knowing many people who have gone through this, I think most get the visa with no problem, I am pretty sure that we cannot say the majority are denied the first time. Yes, even on CFL we have had one who recently had to make the tape. Yes, he was very prepared and yes it was unfair. There doesn't seem to be any real rhyme or reason why GZ does like they do but most are successful on their first interview. Some have suggested that 30 percent are denied pending further evidence. I think it is closer to ten percent.
