If a white latina or a half latin (like Victoria Justice) person experiences racism in America, what would that be for?

I'm just curious since I really, really wanna move to the States. I've never experienced racism or anything of the sort before in my life. I figure racism over there (when it does exist) is almost always about "white supremacy" so technically if I was white why do some people say I MIGHT still experience racism? Plus I'm also "Americanized" meaning I got the American accent, speak English, etc, etc. What would they be racist about? Does it have something to do with "taking jobs" or why?

Thanks in advance ☺️..
