Dual Citizenship

Kiribati does not permit dual citizenship. The Constitution and the Citizenship Act require that a person who acquires citizenship of another country must renounce Kiribati citizenship, and conversely, a foreign national seeking Kiribati citizenship must give up all prior nationalities.

Key provisions:

An I-Kiribati citizen who voluntarily acquires citizenship of another country ceases to be a citizen of Kiribati.
Applicants for naturalization must renounce all other citizenships before the grant is finalized.
The prohibition applies equally to citizens by birth, descent, and naturalization.

Climate context: The prohibition on dual citizenship is increasingly problematic given Kiribati’s existential vulnerability to sea-level rise. With a mean elevation of approximately 2 meters above sea level, Kiribati faces the prospect of becoming uninhabitable within decades. Former President Anote Tong pursued a “migration with dignity” strategy, including the purchase of land in Fiji (the Natoavatu estate on Vanua Levu) as a potential relocation site. Under current law, I-Kiribati citizens who relocate and naturalize elsewhere would lose their Kiribati citizenship — severing their legal connection to a nation that may still exist as a sovereign entity under international law even if submerged. This has prompted calls for constitutional reform to allow dual citizenship, though no amendment has been enacted as of 2026.

Acquisition of Nationality

By Birth

A child born in Kiribati acquires citizenship at birth if at least one parent is a citizen of Kiribati at the time of the birth.

Key notes:

There is no unconditional jus soli. Birth on Kiribati territory alone does not confer citizenship.
The citizenship of the father or mother is determinative, consistent with the jus sanguinis principle modified by territorial birth.

By Descent

A person born outside Kiribati acquires citizenship if at least one parent is an I-Kiribati citizen at the time of the birth, provided the birth is registered with the appropriate Kiribati authorities.

Generational limit: The Citizenship Act imposes restrictions on transmission beyond the first generation born abroad, to prevent indefinite chains of citizenship without a genuine connection to Kiribati.

By Adoption

A child adopted by an I-Kiribati citizen may acquire citizenship if:

The adoption is recognized under Kiribati law.
The child is under 18 at the time of adoption.
The adoption order is granted by a Kiribati court or recognized by Kiribati authorities.

Customary adoption (a common practice in Kiribati and across the Pacific) may be recognized for citizenship purposes if validated through the courts.

By Marriage

Marriage to an I-Kiribati citizen does not automatically confer citizenship. A foreign spouse may apply for naturalization under the standard pathway, though the residency requirement may be reduced at the discretion of the Minister. The spouse must still renounce any other citizenship.

By Naturalization

Requirement	Details
Lawful residence	7 years continuously immediately preceding the application
Good character	Must be of good character as determined by the Minister
Language	Adequate knowledge of Gilbertese or English
Intent to reside	Must intend to continue residing in Kiribati
Renunciation	Must renounce all other citizenships
Ministerial discretion	Naturalization is granted at the discretion of the Minister; there is no automatic right
Fee	AUD 200

Practical note: Due to Kiribati’s small population (approximately 120,000), limited bureaucratic infrastructure, and geographic isolation (33 atolls spread across 3.5 million square kilometers of ocean), the naturalization process can be slow and unpredictable.

Loss and Renunciation

Automatic Loss

An I-Kiribati citizen who voluntarily acquires the citizenship or nationality of another country ceases to be a citizen of Kiribati. This loss is automatic and occurs by operation of law.

Voluntary Renunciation

A citizen may renounce Kiribati citizenship by declaration, provided:

The person holds or has been assured the citizenship of another country.
The person is of full age and capacity.

Deprivation

The government may deprive a naturalized citizen of citizenship if:

Citizenship was obtained by fraud, false representation, or concealment of material facts.
The person has been disloyal or disaffected toward Kiribati.
The person has been ordinarily resident outside Kiribati for a continuous period of 7 years without maintaining a genuine connection.

Citizens by birth or descent cannot be deprived of citizenship.

Restoration of Nationality

There is no formal statutory mechanism for the automatic restoration of Kiribati citizenship once lost. Former citizens must apply for re-naturalization, meeting the standard requirements including the 7-year residency period.

Given the climate threat facing the nation, there have been academic and policy discussions about creating a facilitated restoration pathway for I-Kiribati who naturalized elsewhere but wish to reclaim their citizenship. As of 2026, no such pathway exists.

Stateless Persons and Foundlings

A child found in Kiribati whose parents are unknown is presumed to be a citizen of Kiribati.
The Constitution contains safeguards intended to prevent statelessness among children born in Kiribati who would otherwise have no nationality.
Kiribati is not a signatory to the 1954 Convention relating to the Status of Stateless Persons or the 1961 Convention on the Reduction of Statelessness.

Climate and statelessness: Kiribati presents one of the most novel questions in international nationality law: what happens to the nationality of citizens when a state’s territory becomes uninhabitable or submerged? International law currently has no clear precedent. Kiribati has sought to maintain sovereignty and statehood regardless of physical territory, but the legal status of its citizens in a post-displacement scenario remains unresolved.
