Yes. Individuals must be work-authorized to perform any employment in the United States, even if it is not employment in an employer-employee relationship requiring completion of the Form I-9. Undocumented aliens, or others lacking work authorization, are NOT authorized to be self-employed or to work as independent contractors. Any person who obtains the labor of an independent contractor, knowing that the contractor is not work authorized, is subject to civil penalties under section 274A of the INA.
