A J-1 visa is a type of exchange visitor visa that allows individuals to participate in exchange programs in the United States for a specific period of time.
The J-1 visa does allow for individuals to work while in the United States, but there are certain conditions and restrictions that must be met. The specific terms of the J-1 visa, including any restrictions on employment, will depend on the type of exchange program and the sponsor organization.
In general, J-1 visa holders are allowed to work only in the field related to the program they are participating in and they are required to maintain a full-time student status. They also may have to obtain a work permit or be subject to other government-mandated requirements.
