Engage in business activities at a professional level
Engage in business activities at a professional level means the performance of prearranged business activities for a United States entity, including an individual. It does not authorize the establishment of a business or practice in the United States in which the professional will be, in substance, self-employed. A professional will be deemed to be self-employed if he or she will be rendering services to a corporation or entity of which the professional is the sole or controlling shareholder or owner.
