Non citizens, don't rate the protection of the US Constitution.Hmm. A cynic might respond that the Constitution and Bill of Rights don't actually grant any rights to anybody; they merely protect/guarantee preexisting God Given Unalienable Rights. Assuming that God's care and influence transcends US borders, that word "unalienable" may be of interest. ;-)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
