Hello
I was living in Canada for 12 years I'm a failed refugee too. We got married in Canada but they still send me home. Yes you have a chance to get sponsored and go back to him but let me tell you this it's going to be a hard and long journey. First and foremost if he already gave in the sponsorship application don't wait and given the Arc application. My Arc application just went through it took them three years to process. I'm still waiting for my sponsor visa but at least I can see the end of the tunnel. Don't give up hope everything is possible you guys just have to have proof.
