I have Canadian citizenship and my wife is a Chinese citizen on a study permit, studying in a college. I am looking to apply for inland sponsorship for her. At the same time, because of our financial situation, we were considering if it could be possible for her to stop studying for a while until (hopefully) she becomes a permanent resident, so that we don't have to pay the high international student tuition fees.
The question I have is, how to maintain her legal status in Canada if we submit a sponsorship application in the next couple of months and if she doesn't return to school in September?
My assumptions so far (from my very limited knowledge of the law) are as follows:
She might get "implied status" after I submit the sponsorship application package, but the implied status would still have the conditions of her original study permit (i.e. she needs to study at a DLI). Therefore, she would be in violation of her study permit conditions if she doesn't show up to school, even despite that there is a PR application in progress for her at the IRCC.
She might not even get implied status right away, until I am approved as a sponsor, because until that time, neither her PR application, nor her application for an open work permit ("change conditions of stay ... as a Worker") are even considered
She must have a valid immigration status, as the CBSA will deport her even despite her having a PR application in progress (i.e. it is allowed to submit a PR application as part of a sponsorship even without a status, but it is still not allowed to stay... and as soon as she leaves the country and not allowed back, the inland sponsorship is refused automatically)
I know there is an application to "change conditions of stay as a Visitor" (IMM 5708). I was wondering if this is something anyone ever had to do, or if it sounds too unusual and likely to fail. Also, do any of my assumptions look incorrect, in your opinion?
