Not Just Legalization

The Los Angeles Times notes that the "Gang of 8" proposal could significantly increase the rate of legal immigration:

The U.S. admits about 1 million legal immigrants per year, more than any other country. That number could jump by more than 50% over the next decade under the terms of the immigration reform bill that a bipartisan group of senators expects to unveil as early as Tuesday. The impact would be felt nationwide, but areas that already have large immigrant communities would probably see much of the increase.
The immigration package includes at least four major provisions that would increase the number of legal immigrants, according to people familiar with it. Some of the parts could generate as much controversy as the provisions dealing with those who enter the country illegally or overstay their visas, according to those with long experience of the politics of immigration....
Opponents such as Sen. Jeff Sessions (R-Ala.), who has long opposed measures to increase immigration levels, say new workers would depress wages and crowd out Americans looking for work during a time of persistently high unemployment.
"The masters of the universe in glass towers and suites, they may not be impacted by this, but millions of struggling American families will," Sessions said in an interview Friday. "We do need to be sure we aren't exacerbating unemployment and wage erosion in America."
The surge would come in several ways: The bill aims to eliminate the current backlog of roughly 4 million people waiting to be reunited with family members in the U.S. The 11 million now in the country without legal authorization would be eligible for citizenship only after that backlog was resolved. Reunification efforts would require boosting the number of visas issued each year. To keep the additional inflow under control, the bill would stop allowing adult siblings of immigrants to qualify, but children and parents would continue to be eligible.
In addition to family unification, which allows people into the country permanently, the bill also aims to increase temporary visas for both high-wage and low-wage workers. The number of visas for high-tech workers could nearly double to more than 120,000 per year. At the other end of the wage scale, a new visa system would allow businesses to bring in workers for jobs including janitors, housekeepers and meatpackers. The numbers would start small, but as the unemployment rate declined, it could reach 200,000 a year by the end of the decade. And growers could bring a total of about 330,000 new farmworkers into the country during the decade. At least some of those low-wage temporary workers eventually would be allowed to seek permanent residency.
