A major problem I see with H1-B workers is that they are basically held captive by their employment. If they are let go they'll either have to find another H1-B role at a different company or they will be sent back to their home country. This control companies have over them basically will cause a foreigner to work harder, accept less pay, and also refrain from making complaints against their employers. It's no wonder that US companies like Disney and others abuse the H1-B system.
