I am an Indian citizen with permanent residence from Norway. Having a full time job with sufficient funds. My husband and I are planning to apply for Canadian visa. He has just temporary residence . My husband has a real uncle who gonna sponsor us but my question is during filling of application form should also have to say yes to question ( do you have anyone relative in Canada) it’s not mine uncle who gonna sponsor. So I can’t prove my relationship. What should I do in this situation as a spouse? Please clear my doubts
Your husband's relative is also your relative. Unless they explicitly ask for proof of the relationship, you don't need to provide it.
Also, a "sponsor" is not mandatory, nor is one even helpful in cases such as yours where you can afford to travel to Canada on your own. Your visa application would be just as strong if you were visiting a friend who was no relation at all, or indeed if you were just traveling to Canada for some sightseeing on your own. In fact, it might even be stronger without a relative in Canada, because the officer would be less likely to suspect that you would want to stay in Canada.
