Not sure if you are from CS. But IIT Bombay CS, batch is like the going choice for the top AIR in JEE. Also the program and the prestige associated with it is life long aristocratic privilege. Things like funding, and other support from network and alumni get a whole lot easier.

But even with that much going on for you, I still wouldn't recommend returning for something like this. Not unless you had a US passport in hand.

And for most people who go to US don't have even anything close to this going on for them. So you do the math :)
