Race, yes, but nobody born here asks me "where are you from?" upon first meeting, whereas I get this a lot from europeans and people from more tribal societies.

I'm an American, and I get asked "where are you from?" almost every time I meet a new person here (in America). I look very non-American and have an accent most people find hard to pin down, so I'm thinking that the question is just not posed to people who look and 'speak' very American.

Well, I'm Canadian, so we can't really compare. I look brown, but have a basically Toronto / SF accent.
