Yes, and you notice how this couple had no trouble getting their application accepted, even though the marriage was fake. I can't help but think the racism and sexism of CIC played a role: white Canadian man with a white foreign wife - no questions asked. White Canadian woman with a foreign black husband - well, going through Accra or Nairobi, be prepared for a two year wait, absurd questions at interview, a rejection, and another year wait for an appeal.
Maybe I'm wrong, but I remember reading an interview with a man who was running a mail-order bride website, providing brides from Eastern Europe. He said usually the couple met and corresponded on the internet for a few months, the man then went to meet the young woman, and if everything worked out he'd get married during his two-week stay, go home, and start the sponsorship. And they almost never had a problem getting accepted, and fairly quickly too. When I compare that to my own experiences trying to sponsor someone I've known for 11 years, and the ridiculous questions they asked, I can't help thinking something is wrong with CIC.
