Every country handles these kinds of situations a little bit differently, but as I recall, the Americans actually do not have a security and criminality provision. I'm saying this with a bit of a question mark in my own mind. I know that the Americans actually don't have a direct mechanism like this for citizenship, because the individuals have to apply first under the immigration provision, and it's only by their arriving with an immigrant visa can they actually become a citizen. So Bill C-14 provides a much more direct mechanism for citizenship.
