And when has Congress ever done anything on it?
One irony is that people who believe they’re arguing for something like the “founders’ intents” in this case are arguing something more like “this is what the Founders should have done,” or “this is what the Founders really wanted to do.” But it’s not what they actually did.
At any rate, what the founders actually did, that's in the constitution. Art IV, Sec. 2, 14th amendment, and a power to Congress to makes of naturalization. There is a body of law outside the constitution, more like legal principles (constitution is superior to a statute, due process includes you get to tell your side); and citizenship law between nations is one such body of ancient law. This body of law is WELL KNOWN, to lawyers.
