Post the zero interest rate regime, it's unlikely US will give that much return as it has in the last decade. AT the same time, India is in a better position vs last decade because foreign reserves are stronger, so depreciation probability is lower as well as fundamentals are better - RBI revised its growth forecasts upwards from 6% to 6.8%, capex to GDP has doubled in the last 7 years etc.
Overall, these factors make India a good diversification for X% of your capital, X can be higher if you choose to move to India, and lower if not, but it can be non-zero, provided the friction of investing is removed
