Statehood is a complicated issue. For example in Puerto Rico, there have were several referendums and statehood has never carried a majority.
> On November 6, 2012, eligible voters in the U.S. territory of Puerto Rico were presented with two questions:
> (1) whether they agreed to continue with Puerto Rico's territorial status and (2) to indicate the political status they preferred from three possibilities: statehood, independence, or a sovereign nation in free association with the United States.[29] A full 970,910 (54.0%) voted "No" on the first question, expressing themselves against maintaining the current political status, and 828,077 (46.0%) voted "Yes", to maintain the current political status. Of those who answered on the second question 834,191 (61.2%) chose statehood, 454,768 (33.3%) chose free association, and 74,895 (5.5%) chose independence.[2]
The plurality, 46%, wanted to maintain the status quo. Less than 35% wanted statehood. And 20% wanted to move in the opposite direction: free association or independence.
There was a 2017 referendum which resulted in overwhelming support for statehood only because it was boycotted by the status quo party.
Only a few months ago, a district judge ruled that they should be citizens, but stayed his own order pending appeal. [0]

> The government of American Samoa has opposed automatic citizenship for its residents, arguing it would threaten the territory’s traditional cultural and religious practices.
I’m surprised the local government would prefer “non-citizen national” status.
Automatic full citizenship might be seen as a stepping stone down a slippery slope towards statehood, at least by those who prefer their current status.
Each year DC pays more federal taxes per capita than every other state. In raw dollars it is more than 22 other states. [2] The people of DC want representation to go along with that taxation.
