It is usually not possible to go to the USA and study if you have no sufficient funds to afford the college tuition fees and living costs. However, if you have exceptional academic standings, you may be offered some scholarship from the university, which may ease you financially.

If you show enough funds, the university may offer you an admission, but it’ll be pretty difficult for you to obtain a study visa if you have just enough funds to sustain there. They usually seek for more than enough funds before granting you a visa.

I hope I’m making sense.
