Engage in business activities at a professional level is defined as 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.
Temporary entry is defined as entry without the intent to establish permanent residence.
A temporary period has a reasonable, finite end that does not equate to permanent residence. In order to establish that the alien's entry will be temporary, the alien must demonstrate to the satisfaction of the inspecting immigration officer that his or her work assignment in the United States will end at a predictable time and that he or she will depart upon completion of the assignment.
