liuliu, we are at the same age and almost in the same situation. I am 21 years old and now just started my college for almost half a year. And, I am in a public university too. Anyway, you should not drop out if you are a foreign student. It will be very hard for you to get a VISA to work here without any proper education(diploma or degree). And, assume that you haven't started anything, you should not drop out too. Many successful entrepreneurs dropped out because they have something urgent(their startups) to do rather than their educations. - Mark Zuckerberg dropped out because Facebook was gaining traction. Remember, college is a good place for you to meet various people. You may find someone as driven as you. And, you can always start something together with him/her.
