The US is mostly made of up people who were born in the US. Of course, everyone in the US (including Native Americans) have ancestors who moved here from elsewhere, but that's true everywhere (even within Africa where humans originated, there's tons of movement). Moreover, none of this is relevant as the US government is responsible to its citizens, full stop.
