welcome
and to answer your question, it depends on the college. different colleges have different policies on undocumented students, but i think most community colleges will accept you. If you want to go to a university i would suggest looking into private ones because some of them will offer you aid. and unfortunately there aren't as many scholarships out there for us, but there are a few private ones. here's some links that i used when i was lookin for info.
