If I have only a tourist visa, what sort of activities can I do in the United States?
B-2 visa is only valid for travel to the United States for a temporary visit for pleasure. This includes touring, visiting friends and relatives, visits for rest or medical treatment, participation on conventions, conferences or convocations of fraternal or social organizations, and participation by amateurs - who will receive no remuneration - in musical, sports or similar events or contests. For a visit for business purposes you need a classification B-1 visa. To apply for such a visa follow the instructions on form DS-156.
