Only people who have a visa already may change their status while in the US. Since he has no papers, he cannot apply for anything in the US, nor can you apply for anything FOR him while he's in the US. If he remains here after the age of 18 1/2, he will be under a 10 year ban on returning.
The only way that he can come back is on a K-1 visa, where you would be married within 90 days. You cannot marry until you are both 18. You would have to be able to prove that you could support him.

I like the way the language changes: it used to be 'illegal alien', then it was 'illegal immigrant', then 'undocumented worker', and now it's just an acronym: 'EWI'.
