Recently they received an invitation to join AARP. They are considered property owners and qualified to join. They signed up.

Does anyone know if you have to be a U.S. citizen to get membership in AARP?

AARP excerpt:
"The organization was originally named the American Association of Retired Persons, but in 1999 it officially changed its name to "AARP" to reflect that its focus was no longer American retirees. AARP no longer requires that members be retired, but be at least age 50; it does not extend full membership privileges to applicants who are retired but not yet 50."

I didn't know that owning property in the United States qualified one for AARP membership. I thought you had to be an American over the age of 50.
