Immigration abuse isn’t a single problem. It’s really a series of problems, sometimes overlapping, but not necessarily.
It’s not just, “These guys are crossing the border illegally”, though that’s obviously a big problem. Birth tourism is one of the more obscure and infuriating problems that comes about as a consequence of the terrible idea that anyone who is born in the United States (unless they’re the children of a foreign diplomat) are automatically Americans. Or, birthright citizenship.
There’s no serious basis that just being born in America, regardless of the legal status of your parents, should immediately convey citizenship. It’s an aberration, internationally, where things just don’t work this way. (Much like voting without any ID.)
And the industry of birth tourism has sprung up around the birthright citizenship loophole with, often, Chinese nationals coming to the United States to give birth, and coming away with instant citizenship for their son or daughter.
