I don't expect US politicians to affect change in India at all. I expect them to change the lives of the individuals they allow into the US.

The Indian upper class (doctors, nurses, developers) are poor by US standards. They can become wealthy simply by allowing them to change location. This would benefit us too, as would allowing the poor to come over and sell us cheap house cleaning or dosa preparation services.

Another example: there are about 90k Somalians in the US, mostly refugees from Somalia's earlier troubles. Assuming they have a GDP per capita half the US average, Somalian Americans have a GDP of about $2B. That's about 1/3 the GDP of all of Somalia (approx $6B, pop 10M).

Do you really believe the JOBS Act (the only concrete action the OP attributes to Obama) even comes remotely close to having such an effect?
