You must be related to a veteran who has served overseas in a location of foreign conflict, earning the campaign medals eligible. That veteran can be a living or deceased spouse, parent, child, sibling, grandparent or grandchild.
Step- and adopted parents, children, siblings (and half-siblings), grandparents and grandchildren are considered the same as biological parents, children, siblings, grandparents and grandchildren and may join the VFW Auxiliary under their VFW-eligible veteran.
