I don't live in a lot of places. For example, I don't live in Azerbaijan. Nor do I live in Connecticut. So any "public official" or "elected representative" in Connecticut is just as much a "dual-citizenship foreigner" to me regardless of whether his forebears came over on the Mayflower or he (or his forebears) came from Azerbaijan.
IOW: As far as I'm concerned, Congress is composed of at least 532 foreigners ... (and I'm not so sure about the other three, either ...)
