Comment H1-B and/or specific (Score 1) 465
Both arguments I see are correct. I've personally seen it used to justify an H1-B and I have no doubt the internal promotion after a "public advertisement" arguments are both correct.
Next time I see such a specific placement ad, I may just call up the HR department and ask them whether or not I should bother submitting for a job as it seems they already have someone in mind.
