My partner was an international student and part time worker here for 5 years but had to go home after work visa expired. We have been conjugal partners for over a year now. I want to sponsor her and daughter under family sponsorship - conjugal partner but I understand that might not work. Currently she owns two rental properties here. but she is thinking of buying a business here so she can come and stay in a common -law relationship, eventually marry. Are there restrictions to do it this way?
