The intent of the H-1B provisions is to help employers who cannot otherwise obtain needed business skills and abilities from the U.S. workforce by authorizing the temporary employment of qualified individuals who are not otherwise authorized to work in the United States.
This text is genuinely surprising to me. The only statutes that come close to meeting that goal are the ones that only apply to H-1B dependent employers and wilful violators.
The 1990 legislation creating the H-1B program was pretty specific that it was for getting skills into the country that could not be obtained locally. Considering all the notices that are supposed to be posted. It is abused heavily, but that was the intent.
