Basically if you leave, there is no guarantee you'll be able to reenter canada. If you are unable to reenter then your application is void.
Its up to you if you want to risk it. A visitors record doesnt guarantee you anything.
If you want to be able to leave, why don't you apply outland? You can still be in Canada.
I am wondering if this works for only married couples or for common-law as well.
I live in Common law and i was going to apply outland since it takes faster.
But i was told from YMCA that it's illegal to apply outland when i am living in Canada as Common-law.
That is why i applied Inland and has been waiting freaking 2 years.
