I think you need to look past this to see other interpretations.
1) Sacrificial lambs? The real beneficiaries of H1Bs are much bigger than this and rather than see the goose that laid the golden egg killed, some fall guys at the fringe were necessary to promote the idea that visa abuse is prosecuted, everyone else is following the law, etc.
2) Eliminate competition -- these two guys were undermining someone else's business and were seen as a thorn in their side. It's like a drug dealer calling the cops on another drug dealer.
3) Punish some guys from the wrong social class -- a combination of 1 & 2, really, but make the H1B bad guys "foreigners". I mean, they're probably *terrorists*, too, we should make sure only "Americans" profit from this program.
