Indian Entrepreneurial Success in the US

Of all immigrant groups, entrepreneurs from India are the most successful in the US, across different dimensions, and that is because they have higher levels of education, and also because returns to education are higher in the US. That is one of the conclusions of this interesting paper. There is a lot of specific and interesting information in the paper, for example: 

We find that Indian entrepreneurs are much more successful than the national average in the United States. Indian businesses also perform well in Canada and the United Kingdom, but the evidence is not as strong. In the United States, Indian entrepreneurs earn 60 percent more than white entrepreneurs and have the highest average business income of any immigrant group. (pp. 23-24)

The name of the paper is "Indian Entrepreneurial Success in the United States, Canada and the United Kingdom," by Robert W. Fairlie, Harry A. Krashinsky, Julie M. Zissimopoulos, & Krishna B. Kumar.
At the same time, however, there are some entrepreneurs returning home, and others are being successful somewhere else.
