Hello There!

Both the cases are benefitial. However, if you want to settle abroad, you should go with it as it would open a door to many new and exciting opportunities. An MBA abroad is great as it gives more exposure, and opens a ton of profiles. Also, your pay will be significantly higher for fresh graduates.

The top 20 schools can get you a starting pay of around 15 L - 25 L (average) which for India standards (any tier 1 city) is pretty good. Also you are likely to have a good career trajectory post a top MBA specially in companies that have well defined growth curves.

Hope this helps
