Welcome to the FAQ website covering document topics in Canada.
My boyfriend is from Colombia, and is currently enrolled in school here in Canada. His school visa/permit will expire in march of 2018, so he has not applied for a work permit yet. We intend on getting married, is it helpful to us to get married before his permit? He will be in Canada for 2 1/2 years by march of next year, so could he apply for permanent residency? If he doesn’t get approved for the work permit, will he have to go back to Colombia even if we get married?
If you get married, nothing changes. You need to sponsor him for permanent residence. You can read more about that all over this page.
