Before you get involved in the admissions process, take a moment and read this post. It is probably the most important post in this blog.
I suggest that you think hard if an MBA is really what you want and need. The MBA Admissions Comittees will make sure that your decision is based on valid reasons, so why not start this early in the process before you commit. I'm not trying to scare you or anything, but this is your life, so it is best to make sure in advance that you are on the right track. Plus, it would be a shame to waste a year on writing essays and taking tests only to find out that you don't really want to leave your work, or that your spouse does not want to leave with you abroad.
Do you really want to leave your work for one or two years in order to study? What do you want to gain by that? Are you not satisfied with your career? Do you think an MBA is a stepping stone, and a natural continuation of your career? How can an MBA help your career? Can a different path be more benefitial? Why not pursue a graduate degree in your field? Is the MBA a mean for career change? Do you want to stay in your industry or your company? Do you want to work in general management, investment banking, public office, private equity, consulting, or entrepreneurship? How is that connected to your undergraduate studies and your work history?
Do you have enough work experience? Do you have enough academic background? Are you in the correct age?
You are going to spend 100-200K$ for your studies. That is like buying a house. Like buying 10 cars. Like traveling around the world. Can you handle that? Do you have financial means? How do you feel about getting a loan? Do you want to get into such a financial adventure? Why? How do you plan to pay off the tuition after graduation?
You are going to leave your home country and do a relocation for several years. Are you ok with that? Do you understand that you might have to stay abroad for several years after graduation in order to pay off your tuition? Do you have a family? Discuss your plans with your partner: Are they willing to relocate with you? What are they going to do while you study? Do they have a work permit? Do they want to study (maybe they should apply with you to some schools)? Can you finance your children while you are there? Do you want to live in dorms or student apartments? Do you want to go to USA, Europe, or Asia?
Do you understand that the application process can take more than a year? Can you handle that? Can you handle studying in English?
The answers should come after you do a profound research, talk to people, and understand what a Top-10 MBA is all about. If you decide that you want this badly enough, then you might get into an adventure of a lifetime.
