There are fears the 2020 Census for the United States could leave out American Samoans.
The 2020 survey includes a question regarding citizenship status but leaves out US Nationals as an option, the status given to people born in American Samoa.
American Samoans living in the US raised concern about not being counted properly or being considered foreigners.
American Samoa congresswoman Aumua Amata was asked to look into the issue.
The congresswoman said her staff were seeking answers from the federal government.
The 2020 questionnaire on US citizenship status triggered protests across the mainland when it was announced in March that the question on citizenship status would be reinstated.
Under the citizenship question, there are five options; born in the US; born in Puerto Rico, Guam, US Virgin Islands or Northern Mariana Islands; born abroad of US citizen parent or parents; citizen by naturalization; and not a US citizen.
