Tech companies can’t find talented US citizens???
H-1B workers are sponsored by the employer and therefore are effectively BOUND to that employer and lose market rights and leverage. Same issue with undocumented workers. These workers can therefore be paid a fraction of market rates and worked a much longer work week. Case closed.
Look at the Silicon Valley class action labor lawsuit where the Big Boys colluded and agreed not to poach each others so-called, “talent”.
Look up what some companies say in their SEC filings about H-1B visa workers.
