Your posts are confusing. Is your problem that your parents can’t pay $70k/year or they just don’t want to? There are a lot of students in the US who have dream schools their parents won’t pay for, but colleges only take available sources of income into account, not parents reluctance to part with them. So if the parents won’t pay, the kids go elsewhere.
If your parents’ money is invested in “houses and apartments,” why should US organizations give you need based aid to attend NYU? Shouldn’t your parents consider liquidating some of their assets first? If they’re reluctant to do that, maybe they should consider sending you to a less expensive school.
