USCIS works on supply and demand. They simply process the paperwork.
The Indian Bureaucracy is CORRUPT from the top down. So let us fix our own mistakes first.
US takes care of its citizens and enforces the laws of the land in order to make every citizen feels like a real citizen.
India lacks respect for its own laws and the laws dont make its citizen feel proud of justice served. (that is, there is one law for those with money and another for those without)
Therefore, many Indians leave for the US seeking freedom of Justice.
So if you want to see India prosper put an end to corruption in the legal system and respect the laws written down in the Indian Constitution.
