What is your financial aid question? This looks more like a “chance me” post.
We can’t really give you much info regarding financial aid as you gave us no info on your family income. Most of the schools on this list don’t give merit aid…and the ones that do…it’s very highly competitive.
So…what is your parent family annual income?
Your list is extremely top heavy. Some of the schools on that list accept less than 5% of international applicants. You say you can write an excellent “why this college” essay for ALL of these schools…but the only common denominator I see is they are extremely competitive for admissions.
You need to check each college…IIRC, there are some that have limited funding for international students…and your ability to pay will be factored into the admission decision.
I’m curious…how did you make this list? What is the common thing between Stanford and Middlebury? Or Grinnell and Johns Hopkins?
Are you intending to apply to medical school after undergrad? Why a neuroscience major?
