Undocumented Indian immigrants to the U.S., numbering over half a million, hold a collective spending power of $15.5 billion and contribute $2.8 billion to the federal, state and local tax revenue, according to an American think-tank report.
The report says that they are the top third contributor to the U.S. economy among other undocumented immigrants. Though there are 4.2 million immigrants from Mexico who lack documentation, it adds.
Together, they make up more than 40.8 percent of the 10.3 million undocumented immigrants in the United States.
