I am living in China with my Chinese girlfriend. I have not resided in Canada for the past 10 years and she has never been to Canada. I want to take her on a vacation to Canada and planning to apply for a tourist visa to "visit family or friends". Does immigration Canada consider her to be my common law spouse even though China has no such laws or recognition of common law partners? Should I fill in the IMM 5409E? If so does anyone know where to find a commissioner of oaths in China? Is it different from a Notary Public?
