I still can’t find the story here on FR, but I did manage to find a blog that gives the original story and the curious way that Arkansas authorities managed to suppress it.
It does say Marshallese, so I may have been mistaken about any connection to American Samoa.
"Springdale has become an escape valve for the Marshallese. The small industrial city is host to the largest population of Marshall Islanders outside of the home islands."
"Many islanders call Springdale the land of opportunity, probably unaware that Arkansas license plates once carried that slogan."
Marshallese immigrants benefit from extraordinarily close ties to the United States that were codified when the countries signed the Compact of Free Association in 1986, when the islands gained their independence. Marshallese are allowed to live and work in the United States indefinitely without visas. As a result, few of those who immigrate seek U.S. citizenship."
But it's amazing they all come to Arkansas.
