I need a help for a friend of mine.. This is really important so if you can reply at the earliest it would be great...

Details needed:
1) Which is the type of Visa for doing an MBA in the US? I know its F1 but still confirming

2) What is the type of visa for a dependent? F2 I suppose.
3) What if the dependent prefers to work once she lands in the US as a dependent with the student who himself is on F1?
