I don’t know where you developed your list, but these schools should never have been considered.
What you need to understand is that a number of strong US universities are public schools that were built, with taxes, from the residents of that state. Priority for admission goes to the residents of that state. California’s students and professors built the reputation of those strong UC’s and CSU’s. The UC’s are huge but they still cannot accept, nor fund, every student who wants to attend. No aid for non residents.
As previously mentioned, you are asking for aid to attend those universities. You also said that you had raised $2500 for your club. That must have been difficult. Now, picture having to raise over 30 times that, in less than a year, in order to attend one of those universities. If you have $70k per year somewhere, then you can try to apply, but even then, there are no guarantees.
Google universities that provide scholarships for international students.
Your safeties are in your home country.
