I believe it's not actually forbidden to ask in the US, just forbidden to make a decision based on a protected category, which is why most companies avoid asking. While I'm sure it's happened, I've never seen someone removed from consideration for having something like this on a resume. Also, I see nationality on resumes quite frequently (although still a minority of the time, except in areas like defense.)
