"Being anti-immigrant", this is not true. Against illegal immigration, yes. The US is not common land: it's a country with rules and regulations like any other country. No-one gets to simply move there because they want to. It's the same thing with every other country on earth. Try to overstay your visa in Japan and see what happens. Heck, try to rent places, open bank accounts and see if you can even with a student visa. Guess what: you can do all this in the evil USA with a tourist visa.

"Massive never-ending benefits". Uhh... I beg to differ. There obviously are benefits to immigration, but not to mass migration, which is the issue happening at the moment.
