Dear Joy,
Pursuing PGDM isn't a good move as fee is quite high also placements aren't so good, companies visiting to campus might not be those which one expect.
So, instead of Alliance University, I would suggest you to go for some other colleges which are either offering MBA or PGDM with equivalence to MBA.
Such as:
Christ University
XIME
Manipal
All the very best.

MIB refers to Master of International Business which is designed for export and import operations and from international business point of view. You can do it.
