OP- start at the very beginning.
Let us know which colleges are commutable from home.
Then your state colleges and U’s.
Then we can start to help you build out the list of “further away” places. You should have another sit-down with your parents to show them the federal loans (your loans, not your parents loans). Taking those on is going to give you many more options, and although they require modest living after graduation, won’t make you live on canned soup forever until you pay them off.
I don’t think the overseas plans are viable. None of us can predict what’s going to happen to the exchange rates once Covid ends and/or once the impact of Brexit is apparent. But getting a job overseas with an American passport is likely to be very difficult in 5 years, and interviewing for jobs with US banks while overseas is also going to be difficult.
So Buy American!
