　　The bipartisan group of senators working on immigration reforms is out with a legislation summary. NPR's Ted Robbins, says it's the most sweeping reform in at least 26 years.

It provides a path to legalization and eventually citizenship for many of the estimated 11 million people now in the US illegally. It creates new VISA categories to make legal entry easier and it demands employers use photos to verify a worker's eligibility. The proposal suggested the new border security measures alone could cost an additional $7 billion. Ted Robbins NPR News.
