A Makeover for Immigration Policy?

Another sticking point in the debate over a new bill will be whether to expand guest worker programs for both highly skilled and less-skilled immigrants under the H-1B and H-2B visa programs. The labor union groups AFL-CIO and Change to Win announced a unified stance earlier this month on a plan that would reform but not augment guest worker programs. President Obama has also indicated he does not want additional guest workers in a new bill.

Strong Demand for Guest Workers

"The current broken system has given rise to a three-tier caste worker system in America: citizens, guest workers, and undocumented workers," said Eliseo Medina, executive vice-president of the Service Employees International Union. "This onerous system depresses wages for all workers because too many employers seek out the cheapest, most vulnerable workers in order to gain a competitive advantage." The union groups say that instead of increasing the number of work visas, a government commission should regulate immigration flows according to the economy's needs. That isn't likely to please employers in industries from nursing to food processing to farming, who want to expand guest worker programs. They say they desperately need additional employees.
