Regulations for international students are stricter, due to US immigration laws. International students are allowed by immigration regulations to work on campus, but they need to fulfill three conditions: they must be full time registered students; their work cannot be more than 20 hours per week when school is in session; and J-1 students must obtain written authorization from the international student advisor for any on campus work other than assistantships. International students who hold full time research or teaching assistantships are not allowed to take any other employment on or off campus.
Note that the summer term is not considered a period of regular enrollment for immigration purposes; thus, during this term only, international students may work on campus in addition to their full time RA or TA appointment. Fall term research and teaching staff appointments typically end on January 15, and spring term appointments begin on January 16. Thus, international students holding full time RA or TA positions during the regular academic year remain ineligible for any other compensated work on or off campus.
