No, for working purpose, your MBA degree may not be of much help in abroad. But the knowledge which you acquired during your study would definitely help in your work in related field. For example, I personally apply various HR tools learnt during MBA, in my office (although in a very limited way), and I have been immensely benefited. Moreover, by detailed knowledge of group dynamics has helped me to successfully motivate and control my subordinates. In private sector, you would be able to get more flexibility to apply what you have learnt.
Beware! I question everything and everybody.
