How many hours can you schedule a student, international and/or G.A. employee to work during the break between academic terms?
Federal law restricts international employees in the United States on an F-1 visa from working more than 20 hours per week while school is in session and no more than 40 hours per week when school is in a recess period. If the international employee is in the US on another type of visa (i.e. J-1) then this restriction is not in effect.

For other types of student employees, they may work up to 40 hours per week between terms with the exception of Graduate Assistants. G.A.'s cannot exceed .49 FTE per term and hours worked during the break would count toward that FTE total.
