The 20,000 H-1B advanced degree exemption closed several weeks ago. As reported previously on this blog, employers should immediately assess whether they have any H-1B needs--including whether to file H-1B petitions for F-1 students working pursuant to OPT status early, as well as other candidates who may require H-1B processing--as next year the cap may be reached early if the economy continues to improve.
As far as I can ascertain, domestic migration is much more sluggish in seeking emerging opportunities. Of course, immigration queues usually represent pent up demand. But that doesn't seem to apply to the H-1B visa program.
