The USVA stands for the United States Department of Veterans Affairs. It is a government agency that provides healthcare, benefits, and services to eligible veterans and their families. The USVA also oversees national cemeteries and provides resources for veterans transitioning back to civilian life.
Because of the forum it is probably the USVA or the United States Veterans Affairs. It could however be the United States Volleyball Association or some other obscure group.
