I am a U.S. citizen and my husband is a Canadian citizen. He lives and works in Canada. Orignally we had planned for him to sponser me outside of Canada and I would stay there so that it would be faster. We do not want to live apart for such a long time so have recently considered applying from within Canada. I've been told that if I apply from within Canada that I will not be able to return to the US for visits? Is this true? i was told that I may not be able to re-enter Canada if i leave, and that I would have to re-submit my entire application from outside of Canada. Any help or advice would be appreciated.
