What would happen to the child if the child is a USA resident, but his parents are illegal?

I'm sorry to hear that. But that is part of life and you have to deal with it. Your probably not the only one with the same problem. My brother married a Mexican girl who is only goldigging him because he is an engineer and my brother is providing her with papers. I know that she don't love him, there were even rumors about her saying she didn't love him, sad, but whatever, I warned him, he will get what is coming to him, I guess.
