If you and your wife are separated and not living together then it is not a genuine marriage. I have a lot of empathy and am not "mean". What I am is realistic. You want to know if you could have problems or your sister could have problems later if you don't withdraw. Yes, you could have problems and so could your sister.
You want to see mean? Try a deportation order from CIC for you and your family for misrepresentation.
