Distance/Correspondence MBA

Distance MBA degree certainly adds value to your resume (for a person who completed their graduation). However, there are not many firms which hire candidates with Distance MBA for managerial roles. You ask me for a justification for that? I'd simply say, there are people who had done full-time MBA and are still waiting for jobs.
Having said that, if you have a distance MBA after having Masters in your technical field that might get you into a pretty decent job. No one can assure it though.
You can use the knowledge you gained through that distance course to become a better professional and climb up the organizational ladder once you get into the firm but when it comes to the opportunities, my word still stands. It is hard to get into managerial roles with a distance MBA with graduation. This is the current status in India when it comes to opportunities for candidates successfully completing their distance MBA.
Pursuing MBA through correspondence will give you knowledge if you really put in the required effort but when it comes to a job abroad, it is very difficult. Let's hit the reality and have a look at supply-demand graph. We are having more supply (people completing full-time MBA) compared to demand even overseas. So, if you have a chance, prefer doing full time MBA which will fetch you a good job in India or abroad depending upon the institute you pursue your MBA.
Hope you got a fair idea of what really is happening in India and around the world. I sincerely wish you will take the right decision.
All the very best.
