My son-in-law has been on the receiving end of racism plenty of times since coming to America when he was a teen; stopped by cops and asked whose car he was driving, as if a young black man couldn't possibly own a nice car, guards at WalMart putting their hands on their guns as he walked in, etc. He has never been naive enough to believe they would know any difference from him or an American of African descent. Of course, all he has to do is start talking and his accent makes it obvious he was not raised here, but that doesn't stop the racists.
