I am wondering why you want to come to the US for university.
Do you have good options in your home country? Is your home country a safe place for you to live and study?
In most cases international students who graduate from university in the US are expected to leave the US and return to their home country very quickly after graduation. There are a lot of very good universities here. However, most are expensive, and there are also a lot of very good universities elsewhere.
Whether your total budget of US $100,000 would be sufficient at schools in the US would depend upon the school, and how much aid you qualify for (whether need based or merit based). There are quite a few universities in Canada where this budget would be sufficient, and where a straight A high school grades plus a 1450 SAT would make admissions very likely.
What would you like to study? What do you want in a university?
