Businessweek has a lengthy article discussing the IV rally and the evolution of the legal immigrant grassroots movement. Favorite quote:

Still, Kapoor's group is not to be taken lightly. Immigration Voice has
evolved quickly from a small Internet community set up for skilled
workers to share ideas and experiences into a well-organized political force
(BusinessWeek, 7/19/07). Over the summer the group organized a series
of events modeled after the nonviolent protests of Mahatma Gandhi and won reversal of a key U.S. State Dept. decision
(BusinessWeek, 7/17/07). Now, Kapoor and other top members are in
regular contact with elected officials and heads of government agencies
such as the Homeland Security Dept.
