As I said, you need to look at the application dates. You still see enourmous numbers for recent years.
But the way they make the listing it makes things look worse. Over and over in there you'll see the same company with numerous identical listings, probably they're the same thing getting counted twice. As I said when looking at one of your own links (
http://www.nomoreh1b.com/h1-bCostPerState.aspx ) it clear this is only a problem is certain states, oddly enough all Democrat strongholds. And even in those states the depth of the problem is arguable because we have no corolative data between H1B's field of work and the unemployment numbers within those fields. There's a lot of assumptions built into saying H1Bs are responsible for the unemployment numbers, especially given the consentration of H1Bs in tech and the dot-com meltdown (which had its roots in bad business "plans").
