hello everyone. I have been in a relationship for 10 years to an American citizen. We have 2 Canadian born children. He was living here illegally for 10 years, we have had many hardships and stress dealing with a corrupt system here in Canada. He was deported once. He hasn't had any ID in 16 years. He just went back to the states to get his ID and lisence and all that so we can try to move our family down there.
What I want to know is what is the best way to do it....should I get my kids dual citizenship before even going down? Should I go down as a visitor and then marry him? We are not legally married because he could never prove who he was. I have been reading about the K1 visa for fiancees....he has to apply for that though right? I can't do it?
I just want to know if you forsee any problems. We just want to be together and not have to live in fear we need to get on with our lives.

thanks a lot
