FYI better not to use silly terms like 'US-ian' as they are confusing and cause problems while solving none. Just stick to the standard 'American', context makes it clear what you mean :)
Haha :-) - fine, hope no offence taken. :-) (none was intended) It came with the flow, flow was - US-... -Government, -Citizens, -Dollar, and then when it came to "people of the world that are not US citizens" (but are users of US dollars) programatically is seems to my compute mind, it came as "non-US-ians" fits that set of people well, and plus tallies with the "US-this-and-that" of the wordings prior. I'm originally from the Balkans, and so cognisant and got some experience with "verbal mines" and nuances in all manner of names and naming-s. I intuit what you are saying. :-) thanks
