Change tourist visa to study visa.

You can get a student visa only if you have I20, the admission notice and all kinds of supporting materials issued by the school. You can't turn. Even if you work in the United States, you don't have legal status and insurance. The money you pay for a once-in-a-lifetime disease is terrible. The study visa is related to the credits and grades of the course. Failure or insufficient credits will lead to the risk of visa cancellation. If found, the Immigration Bureau can propose repatriation.
