So, that was my first question; when the main applicant is submitting the application and have to include her, what kind of legal "permit" would she be granted?
You have to pick. OWP allows a spouse to work.
TRV or SOWP might be denied. Yes international students are able to apply for their spouses to accompany them but not all get approved.
Visitor Visa for +9 months? If this is the case, at least she would be allowed to receive coverage in Alberta Care or other Province benefit.
No don't believe the the spouse of an international student has access to any form of benefits of healthcare especially on a TRV. If the spouse is working for a certain amount of time yes they likely qualify for coverage (depends on province).
What the options are?
