News Summary: Tech, labor spar on immigration

VISA BATTLE: Wrangling over efforts to increase the number of visas for high-tech foreign workers has strained a bipartisan deal in the Senate on immigration reform, showcased the power of big labor and splintered a once-chummy group of elite tech leaders hoping to make inroads in Washington.

CHEAP LABOR?: Technology companies cite a shortfall in the number of Americans skilled in computer programming and engineering. But unions and some Democrats see the push by Facebook's Mark Zuckerberg to expand the number of visas as an attempt to dilute a lucrative job market with cheap, indentured labor.

COMPLEX ANSWER: The answer depends as much on new technologies and the U.S. education system's ability to keep up as on the immigration law itself.
