For your other question about teaching, I believe it depends on your NOC if its over D or not. However, my advice is call MIDI and ask instead of asking here.. people here only want to know the timelines of others. You can even see the selfishness in the petition they made not mentioning applicants that are cap-exempt that actually contributed to this Quebec economy not like them, only paying 800 dollars and thinking they actually deserve a better life here!
