Foreign Tech Workers: Do We Need Them

Many immigrants with technical skills are admitted temporarily with H-1B visas and eventually qualify for a green card. But the program is controversial. To some it is "creaming" of talent that is needed in poor countries. To other it is cheap competition for American workers. The latter argument takes on added sting with the recession and growing joblessness. But employers argue that the talent is needed and the temporary visas is better than outsourcing the jobs. The New York Times' series "Remade in America" visits the issue from different perspectives.
