Um, being an immigrated legal permanent resident does not give you any representation. The problem of taxation without representation is not that immigration is hard, it's that you are taxed, and you have no representation.

You can be a temporary (think H1s, student visas, etc) resident, a provisional permanent resident (essentially it's what lets you be a resident for the extended period it takes to approve a green card in which your original work permit might expire), or a permanent resident (i.e. a green card), and in all those cases you pay at minimum the same taxes as citizens.
