The maximum length of stay is determined by the State Department and is based in part on typical university schedules in each nation.
The types of jobs on offer include sales-people, cashiers, hosts and staff in hotels, restaurants or entertainment parks.
Once a J-1 visitor's program ends, he or she may remain in the United States for an additional 30 days, often referred to as a "grace period", in order to prepare for departure from the country.
The minimal and the maximal duration of stay are determined by the specific J-1 category under which an exchange visitor is admitted into the United States.
Agencies are also engaged in health and safety issues and are available to help solve any problems which may arise for students during their stay in the USA.
