Attendance

       do not attend at least 85% of all classes will be considered "Out of  Status." If you
       are considered  "Out of Status,' you will not be allowed to extend your period of study,
       take an  authorized  vacation, or transfer to  another school. The only exception is a
       prolonged illness, verified by a  medical doctor (i.e., doctor's report).

        of address during your course at VIU must be reported within 10 days.

        studies if they have completed at least one semester at VIU. Those who are attending degree programs should obey
        the university regulations as explained in student handbook.
 2.   If you plan to take a vacation inside the U.S, you must  notify the ISA (International
          Student Advisor) at least one week before your departure.
 3.   If you plan to take a vacation outside the United States (if your visa allows more than one
      entry), you must notify the ISA at least one week before your departure. Also you must have
