Vivek is a clever dude but a softie, US only needs a few of those indians.
Not too many.
Too many indians coming to the US will change the demographics in the future.
US need to stabilize with their white population.
Unless they are summoned only to do their engineering and then sent back, but thats highly unlikely. They will settle and get lots of children, and US can´t have that.
Summoning a million Viveks to the US will create too much trouble
Can¨t have too many people thinking in a Curry-esque manner.
