GTRE for sure. In fact I am in touch with a couple contacts there already. So that or a startup (depending on how the MSME sector is for aviation propulsion etc)
I would like to return and contribute to my motherland in say 5 - 10 years from now. Right now I am busy in still learning and developing things that I simply cannot do in India...and I feel India can benefit greatly from....I don't want to be just another brick in the wall when I get back
For my hobby I want to develop a good school in a backward area....I am hoping Modi pushes through good education reform so private sector can enter education market more easily than now (with less red tape).
The phenomenon you are talking about (reverse brain drain) has already started, please check this thread:
