Boundaries of federal laws
An inherent authority is bestowed on the states, in order to protect the welfare of the public and activities such as the licensing of business firms and the issuance of a driver’s license fall within the scope of this authority. State and local governments can specify the requirements for such licensing; however, these specifications have to be within the boundaries of federal laws and the Constitution. As such licensing of businesses would be concomitant on the acceptance of that business to ensure that its employees’ status was legal and that it permits them to work in the US.
