Do bare in mind that most funding, at these universities comes from the government (which gets its funding from American taxpayers) for mostly domestic applicants.
The schools are not obligated to fund international students.
They don’t give full funding to US citizens, and, since most US students can’t afford to pay, their parents take out huge loans to attend.
Your sense of entitlement is absurd.
The schools don’t have to admit you and they don’t have to give you funds to attend.
The schools fund you with their own formulas; you don’t tell them what you need, they tell you what they can give you. Don’t expect a full ride because that is not going to happen.
You are aware that you also need to pay your own transportation, living expenses, and the required health insurance?
Also, if you are admitted anywhere, once you graduate, you are expected to return to your country. Immigration rules are strict. Employers are required to hire US citizens first. If you apply for jobs in the tech industry, expect that employers will NOT be willing to sponsor a non citizen, nor wait, nor pay visa fees. There are plenty of US candidates who need to pay back their loans.
Why apply? You should really consider going to universities in your country because there is a likelihood that you won’t be accepted anywhere in the US since you indicate you need a huge amount of cash.
