Membership in ISVA is based on a calendar year that runs from January 1 – December 31 annually. ISVA welcomes new members to join throughout the year.  Benefits begin with date of dues payment until the end of the same calendar year. Dues are not pro-rated based on the date joined. It is our policy, however, that each person becoming a new member after November 1 shall be considered as paying dues in advance of the coming calendar year.  Renewal of membership is due January 1 of each year.
