Nonetheless, Miano"s report shows that wages paid to H-1B workers in computer programming occupations had a mean salary of $52,312, while the OES mean was $67,700; a difference of $15,388. The report also lists the OES median salary as $65,003, or $12,691 higher than the H-1B median.

When you look at computer job titles by state, California has one of the biggest differentials between OES salaries and H-1B salaries. The average salary for a programmer in California is $73,960, according to the OES. The average salary paid to an H-1B visa worker for the same job is $53,387; a difference of $20,573.

Here are some other interesting national wage comparisons: The mean salary of an H-1B computer scientist is $78,169, versus $90,146 according to the OES. For an H-1B network analyst, the mean salary is $55,358, versus the OES mean salary of $64,799. And for the title "system administrator," there was a $17,478 difference in salary between the H-1B mean and the OES mean.

H-1B visa workers were also concentrated at the bottom end of the wage scale, with the majority of H-1B visa workers in the 10-24 percentile range. "That means the largest concentration of H-1B workers make less than [the] highest 75 percent of the U.S. wage earners," the report notes.

While it would be difficult to prove that any one particular employer is hiring foreign workers to pay less, the statistics show us that, for whatever reason, this is exactly what is happening on a nationwide basis. Miano says lobbyists will admit that a small number of companies are abusing the H-1B program, but what he has found in this research is that almost everyone is abusing it.

"Abuse is by far more common than legitimate use," he says.
