I currently have a USA B-1 visa (visitor visa) that's valid for the next five years (approx), and I will be applying for an F-1 visa (student visa) soon, because I plan to start an MBA program at Yale this Fall. Does anybody know if my B-1 visa will be voided when I apply for the F-1? Thanks in advance for any insight that anybody is able to offer!
No, you won't be giving anything up. You are allowed to have multiple visas. However, you have to be very careful when you re-enter the US with 2 visas. You want to make sure you enter with the correct status - "Student" vs. "Tourist"
Lots of headache can happen if you are processed at the passport control as a tourist instead of a student. You can probably google and find some additional tips and information about ways to make sure a mistake does not happen on immigration/visa forums.
Good Luck!
