This New York Times article explores the phenomenon of Indians moving from the West back to India, emigrating in the opposite direction of their parents. India established the Overseas Citizen of India card in 2008, allowing lifetime visa-free entry to the country. Already more than a quarter of a million expats had signed up.

Nice post. I think that because so many Americans concentrate on immigration reform, little attention is paid to emigration patterns in our country.
The 2004 Bollywood movie Swades was a call to action for educated, wealthy Indians living abroad to move back to India and share their resources. It did terribly in Indian theaters, but was a sensation abroad.
There is clearly an Indian interest in returning to the homeland, as the new visa card has drummed up so much interest as well. This will be an great geographic pattern to study in coming years- thanks for the info!
