May of you may be familiar with Professor Vivek Wadhwa from his columns in BusinessWeek and his major papers published on skilled worker immigration. I got to meet Professor Wadhwa when we both spoke at an ImmigrationWorksUSA conference a few months back. He gave a very informative presentation using the slides I'm attaching. Professor Wadhwa kindly agreed to let me publish them on my blog so readers could benefit. Many thanks Professor Wadhwa.
