Hi all,

Two years ago, I came to Canada in student visa for my PhD. After few months in Canada, I sponsored my wife for her stay here and she got dependent visa under visitor category from India for nearly 4 years (her visitor visa expires in December 2010 when my study permit expires). After she joined me nearly for 1 year, she went back Nepal, stayed there about 6 months and then later had divorce from me about 2 months ago. Now, our 5 years old son lives with my parents in Nepal, whom we did not bring to Canada when my wife joined me those time.

My ex-wife recently told me (she is still in my touch as she frequently visits our home to see our son) that she does not have a good life in Nepal, so she wants to come to Canada to work or study here using the same visitor visa (she still has a valid visitor visa which I sponsored) telling the Canadian authority that she is still my wife if enquired at the port of entry. But, those time, I was the sponsor for her cost and took responsibility for everything during her stay here when she applied for dependent visa. Now, I am no longer her sponsor if she makes any visit to Canada. Next, it is legally and morally unacceptable if she uses the same visitor visa to come to Canada as my wife.

I told my ex-wife not to misuse that visa in coming to Canada and I also want to stop her from doing so if possible. How can I do this? Do I need to inform Canadian authority that I am already divorced from her and am no longer responsible for her any trip to Canada? Can I request them to revoke her visitor visa she obtained as a dependent of mine at those time? I am planning to visit Nepal sometime soon, get married and bring my new wife and son to Canada. If my ex-wife comes to Canada on that visa, will my new wife have any problem in obtaining visa?

Thanks for your suggestions in advance!
