My wife received an ITA. I was listed as an non-accompanied spouse in the beginning. However, I don't want her to change it to accompanying because it would lower her score below the threshold and cause her to be ineligible to apply for PR. Can she sponsor me at a later date being that she already living in Canada on a post graduate work permit? Also how long it will take her to get me there if she can? Furthermore, is it possible for me to apply for a work permit?
