Ive tried researching what to do for quite some time with no results so ive come here hoping someone could help me out?
Iam a
canadian citizen who moved here as a
minor and had no
SIN. Therefore im currently 20 now and still dont have one, meaning i cant work or go to school in the USA. Im planning to move home in a few months. But ive lost my original
Birth Certificate. I have a photocopy. Im not sure of how to get a new one or if that is needed for the process? And after that is figured out what do i need to do to be able to be allowed back in Canada? IM wanting to stay in Canada after that-permanently. I have been in the US since i was 10. Im just not sure what i need to do in order to make this all happen

I just know its time for me to move home. Can anybody help???
