What of that, expert?

edit: here's a page that explains how immigration law has worked through history and it's utterly clear that Congress' efforts to manage immigration were exactly as intended from the beginning.

Naturalization is the process by which an immigrant may become a citizen. It has absolutely nothing to do with how someone becomes an immigrant in the first place. Having power to make rules over naturalization does not grant any power whatsoever over immigration.

Congress is PROHIBITED from making legislating anything not specifically enumerated in the Constitution and PROHIBITED from having any "implied" powers.
