I would recommend Florida International University. They have amazing programs for international students. It’s a very welcoming atmosphere and the campus is gorgeous. The school isn’t expensive at all and they offer scholarships specific to international students. I have met a lot of students from there that got into top dental schools and just about any graduate school they wanted. I honestly have not met one graduate from there that isn’t where they want to be, they truly take care of you. Check it out www.fiu.edu
