Alpha Gamma Delta has several chapters in Canada so we stretch from the University of Hawaii (only NPC sorority on campus) to Ontario and Nova Scotia (sorry, I'm not up on my Canadian geography so I don't know which is fartherest NE).
I do know of AGD's from other countries that are going to schools in the U.S.
As for becoming "Americanized", that could happen almost anywhere, college or not..., even going from Northern U.S. to Southern U.S. and start saying "y'all" and loving barbeque. Also for example, perhaps I would go to a school in Germany and become "Germanized", lol!
Probably sound funnier with my "Southern accent".
