I respect your opinion, but why not? I dont want o carry the baggage thinking about if and when they come back what would i do.
I really appreciate your honesty and I think that's what makes this country so amazing. While I don't encourage abuse of system, I do understand stuff gets out of control sometimes and you seem like genuinely struggling.
1. Remember, you are not doing anything illegal by moving province as Canada gave you the right to do so(Don't listen to what people say in this forum).
2. If you contact SINP or CIC to admit what is happening, you would be seen as admitting guilt which is absolutely unnecessary! Chances are CIC won't even know how to react to your situation. Like I mentioned earlier, I am yet to come across a person whose PR was revoked due to moving provinces.
3. The only thing I will do, is stay in Sask. till December.31 to be eligible to file taxes there before I move. It will probably take you a month to go through hiring process anyways.
4. Don't feel bad, there will be plenty of opportunity for you down the road to give back to the community.
