What is the H-1B employment requirement for for the petitioning U.S. employer?
According to the USCIS, H-1B aliens may only work for the petitioning U.S. employer, and only in the H-1B activities described in the petition. The petitioning U.S. employer may place the H-1B worker on the worksite of another employer if all applicable rules of DOL are followed. H-1B aliens may work for more than one U.S. employer, but must have a Form I-129 petition approved by each employer. Enforcement of these rules depends upon the employee, however. The Department of Labor has neither the authority nor the manpower to investigate violations of these rules unless and until a complaint is made.
