An American Samoan senator, Alo Dr. Paul Stevenson, says he will lodge an objection with the US state department to Samoa's plans to open a consulate in the territory.
This comes after a stand-off between the two Samoas over the tightening of travel rules.
Alo has accused Samoa of discrimination for asking American Samoans to get a permit to travel to Samoa.
He says at the same time a US citizen carrying the same US passport will not be required to do so.
Alo says the new Samoan policy is extreme and alarming.
