Not to be PC, but "American" means U.S. to some, but not to others who interpret American as any of the nations in North, Central, or South America, not solely the U.S., but including it. Canadians are American, as are Mexicans, and etc. etc. I once corrected myself to a Canadian colleague and he immediately assumed the my boss had so instructed me. Ha! I put him straight on that one. I think the OP meant American as in U.S.
