Hi ruhanichawla,
You ask a rather broad question, so you'll have to consider the details of what you're asking about:
1) What type of MBA are you considering?
2) What School/Program is that MBA going to be from?
3) What field/company do you want to work in/for?
4) What type of Alumni base/connections will the School be able to provide you?
Etc.
Thankfully, all of these questions can be researched, but you really should think about what YOU want your MBA to do for you. In that way, you can choose the 'right' Degree and School for the career path that you want to be on.
