There are only a very short list of universities in the US that provide full need based aid for international students. 90 on the TOEFL and 1100 on the SAT is not going to be enough to get accepted to any of them.
University in the US is very expensive for students unless they can qualify for a LOT of financial aid.
Also, international students who study in the US are normally expected to return home after they graduate.
I am sorry to be giving bad news, but I do not know how you could make your dream come true to move to the US.
