marcirose,
if you don't mind my asking,
how old are you and how many times have you tried to get into US schools?
If you are in your 20's and this was only your first year to try for US schools and you are on 3 wait lists, it might be worthwhile to try again @US schools next year. In fact I think it WOULD be. I know it seems like too long to wait, but it would make your life easier later, b/c it will be easier to get the residency you want, and might cost you significantly less money than going to St. George. I know the 1 year wait seems like a long time, and I guess there are no guarantees of getting into a US school even next year, but if you are good enough to get wait listed @3 US schools they you must have a pretty good application.
