I'm a US citizen living in the US and my wife is from Vietnam. We applied for an immigration visa to the US 2 times. Now we don't know what to do its been three years. Our choices are limited to me moving to VN, or both of us moving to a third country. She does not want to stay in VN. What are the chances of me getting a job in Canada and having my wife immigrate to Canada? Do I need an immigration visa in order to sponsor my wife in Canada?
