Citizens from the following countries are eligible for support under the PIC Fund: the Cook Islands, Federated States of Micronesia, French Polynesia, Fiji, Kiribati, Nauru, New Caledonia, Niue, Palau, Papua New Guinea, the Republic of Marshall Islands, Samoa, Solomon Islands, Tokelau, Tonga, Tuvalu, Vanuatu, and Wallis and Futuna.
