I know in the US Universities you can get scholarships if you're poor and have no parental support, that will pay a lot, if not all of tuition and fees. Also, jobs can always be found near campuses.

The two biggest public Universities in Washington state have said they'll pay all tuition and fees for someone who qualifies for some specific grants - Wa state need grants and federal Pell grants (and maybe others). I think being an American citizen would help.

But like others have said; this is a big thing, and you need to be sure of what you are doing.

Best of Luck,
