Where do you want to attend dental school? In the US?
Can you work in Korea with a US dental education?
Can you even get into US dental schools as an international student? Most medical schools here don’t admit any international students at all, but I don’t know about the policies of dental schools.
Before you ask your family to spend several hundred thousands of dollars on your education here, make certain that your goal is readily achievable.
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
