13 outsourcing companies took nearly one-third of all H-1B visas in 2014.

The outsourcing companies dominate the visa program by flooding the system with applications.

With more applications, the number of visas given to outsourcing companies has risen sharply.

Many H-1B workers earn salaries below market rates.

The vast majority of H-1B workers are from India. The top outsourcing firms primarily bring temporary workers from India. American companies like Microsoft, Google and Apple have drawn from a wider range of countries, including China and Canada, for their H-1B workers. But in 2014, 70 percent of the H-1B visas went to workers from India, according to the Department of Homeland Security.
