OK - this is why I asked about budget. This is a HUGE issue - and yes, you might end up at community college. You won’t be able to borrow enough to fund college - certainly not at a school with nuclear engineering.
Is the non-contribution by choice or are they unable to afford anything?
Oregon has a promise grant for low income families - but I don’t know if it covers housing, etc.
If your budget issue is due to low income, your school counselor should be able to help you.
If it’s by choice - i.e. they can afford but don’t want to, that’s a bigger issue - as you’d have to apply and hope for full rides - and those are unlikely and certainly at schools with your intended major.
