One of my friends got 5yrs multiple visa of the USA. He is going to come in the USA by the end of March. However, he wants to join the college and have some college degree but before that he needs change his visa status from B1B1 to F1. Do you guys have any idea how to change the visa status from B1B2 to F1. Or simply What are the ways does he need to follow to change his visa status.
