The big blue ones?

Thank you very much for this brief heads-up. I like the way you treat the terms and I guess I should also follow it myself (pls see below). Moreover, it has such deep historical roots.

I'm a life-long sci-fi fan and so are my sons. Up to this point all aliens, whether resident or non-resident, were exclusively extraterrestrial for me, especially since Area 51. Now I see the US tax system regards them quite differently so that their legality is more dependent on their clean taxation history than their ex(tra)terr(estr|itor)ial origin. From that standpoint, your peaceful picture is quite casual and the word order may be safely changed to 'resident extraterrestrial aliens'.

I gather that's one of the strongest points in your democracy model.
