The intent of the H1B is supposedly to provide foreign workers for labor categories where no American national can be found to perform the work.  If there is any training going on there at all, that is proof of fraud.  If the ones doing the training are American nationals, that just makes it more egregious.<p>Hadean justice would alter the H1B visa category such that the guest worker could perform no function for the company other than to train American nationals to perform adequately in the labor category that required the imported foreign worker.<p>Clearly, if it is advantageous to import a skill, it would be more advantageous to replicate it during the limited time that it is available.
