what does it feel to be well documented in usa?

tell me please...
what does it feel like?
i want to know,
am missing out on so much..
i do not want to lead a non productive life..
i make it a point to serve and help in my community,
without an identity card, i feel am an outsider,
without my papers i feel am an outsider,
indeed the descriptive "alien" is apt,
i feel am from a non-earth planet,
i feel am being done a favor,
to breathe, to smile, to look, to walk,
i look at my back always,
what if the police comes for me?
am an alien!
perhaps am a species that collects human brains!!
or am a collector of human hair?
tell me what does it feel like to be in status?
