That's rich...
You are probably thinking about Pakistani expats, who once they leave don't prefer to come back to your country.
Where as Indians keep one foot firmly in India, does not matter where we are.
We earn in other countries but we invest in India. This is one of the best kept secrets of India.
You should check the amount of money NRI's invest in India and then talk..
Let me tell u the difference between us and other expats.
My name is hard to spell, typical south Indian tongue twister and very long. I proudly wear use it in every country I go. You should check out what Chinese calls themselves in US or Australia...
I could give you a lot of material but at this point, I frankly don't care.
I may or may not get foreign passport. I already rejected US passport, I may reject Aussie one as well or I may take it because the social security here is one of the best in the world BUT all my money will always be invested in India, every dollar I earned and saved is invested in India.
