Do stepchildren qualify for USAA even if they were adults when their parent married their stepparent?

USAA membership eligibility is primarily based on the military service of the member or their immediate family. Stepchildren may be eligible for USAA membership if their stepparent is an eligible member and they meet certain criteria. To be eligible, the stepparent must have served in the military and have a USAA membership themselves. Additionally, the stepchild must have been legally adopted by the stepparent or have been under their legal guardianship prior to turning 18. If the stepchild was not legally adopted or under legal guardianship before turning 18, they may still be eligible for USAA membership if they are a biological or legally adopted child of an eligible USAA member. In this case, the biological or adopted child would need to be a parent of the stepchild, and the stepchild would need to meet all other eligibility requirements. It is important to note that each case is unique, and eligibility for USAA membership will ultimately be determined by the organization based on the specific circumstances of the individual. It is recommended to contact USAA directly to discuss eligibility requirements and any questions or concerns regarding membership.
