When can a B-1/B-2 visa be used instead of a J visa?
Some activities that are done on a J visa are also permitted on B-1/B-2 visa (temporary visitor for business or pleasure). Study that is incidental to the trip is permitted on a visitor visa. The determining factor is the traveler’s primary purpose in going to the United States. For example, during a vacation to the United States on a B-1/B-2 visa, you may take a two-day cooking class for your enjoyment. A consular officer will determine the class of visa you will need based on the purpose of your travel.
