Hi, I am a Canadian citizen living in the US. I am planning on moving back to Canada in February 2020. I want to sponsor my girlfriend for permanent resident status. She is an American citizen. We have been together for 2.5 years but have only been living together for the last 4.5 months, ie, joint utility, cable bills, etc...My question is can we start the sponsorship process NOW, or should we wait for the full 12 months of living together. Also, is this is fairly simple process we can do on our own or should we use a lawyer? Many thanks in advance, Adam
