as far as i know, if you don't enter the country with the primary application, you can't after, and have to re-apply for PR. As in new app, probably under spousal sponsorshipThanks mufarina,
What if your mom join your dad later? Still can’t get her PR? Thought it’s okay... that’s the reason why I didn’t ask CIC to cancel my dad visa as probably he change his mind later....
Is there any expiration date on your dad visa? I think it’s one year...
