It would be your decision, but I don't think consultant can make any difference. Why don't you just simply write to CIC and accept your mistake that you didn't mention your wife in your papers to earn some extra points because you were not interested in accompanying her, and you filled your forms by yourself without having a proper knowledge of immigration rules. Of course, your current application would be rejected, but in this way hopefully you could avoid 5 years ban.@Natz_K Your case is very complicated...If I was you I would have visited a professional immigration consultant or lawyer and sought their advice. Here in this forum, none of us are true professionals so plz don't waste your valuable time as you have only 7 days to reply and visit a consultant or lawyer asap.
