The Union Internationale de Spéléologie (UIS) is the international body for caving and speleology. Formed in 1965, its voting members consist of a delegate from each member country. This delegate represents the country's cavers and speleologists, rather than its national body(s). An elected Bureau runs the affairs of the UIS between once-every-four-years General Assembly meetings held at the international Congresses. The actual speleological work of the UIS is done by members of its Commissions and Working Groups, which are open to everyone who is interested.
