Isn't this just too hot of a political issue for Congress and Obama? Opponents argue that the visa policies are partly to blame for declining computer science enrollments by Americans. Because the H-1B program offers the prospect of employment after graduation, it encourages foreign students to enroll, and those large enrollments are discouraging U.S. students from entering IT-related fields.

This argument may rise again during the next debate on the visa issue, but it's not new and it's not an argument that finds support in Obama's platform. The bottom line is this: Obama has said nothing during the campaign that rules out either H-1B or green card increases. If anything, his tech platform, especially his plan to boost research funding, offers an argument for encouraging foreign enrollments and increasing access to visas.
