You've got a whole bunch of red flags, from being banned because you probably misrepresented (don't blame your agent - you were very much involved and had to sign off on everything before it was sent off) to now your wife spending too much time outside of Canada to where she is probably not eligible to sponsor you anymore. Good luck to you, I would expect a lot of scrutiny and for the sponsorship to take longer than normal.From day one , i knw my interview will come for sure , bcz in 2012 , i applied for student visa but bcz of some stupid agent i got refusal and banned for 2 years ! So i wont allow to entered canada till 2014 ! I was banned ! Might be this is a reason otherwise our case was cleared !
