Dual Citizenship

Nauru’s approach to dual citizenship is conditional, with different rules applying to citizens by birth and naturalized citizens.

Key provisions:

  • Citizens of Nauru by birth who acquire a foreign citizenship do not automatically lose Nauruan citizenship in all cases. The law provides some tolerance for dual nationality among birth citizens.
  • Naturalized citizens must renounce all prior citizenships as a condition of acquiring Nauruan nationality.
  • The Constitution gives Parliament the power to legislate on citizenship matters, and the rules have evolved over time.

Practical context: Nauru is the world’s third-smallest state by area (21 square kilometers) and has a population of approximately 12,500. The very small size of the polity means that citizenship decisions are often handled at the Cabinet level with a degree of personal attention uncommon in larger nations. The Nauruan diaspora, primarily in Australia, faces similar dual-citizenship tensions as other Pacific Island communities.

Acquisition of Nationality

By Birth

A person born in Nauru acquires citizenship if they are of Nauruan descent — meaning at least one parent is Nauruan or the person belongs to the Nauruan community as defined by law.

Key notes:

  • There is no unconditional jus soli. Birth on Nauru alone does not confer citizenship.
  • The concept of “Nauruan” is tied to communal identity and descent, reflecting the island’s close-knit social structure.
  • The Nauruan Community Ordinance 1956 historically defined who qualifies as a member of the Nauruan community.

By Descent

Citizenship by descent is the primary basis for Nauruan nationality. A person born outside Nauru to at least one Nauruan parent acquires citizenship, provided the birth is registered with Nauruan authorities.

Conditions:

  • At least one parent must be a Nauruan citizen at the time of the child’s birth.
  • Registration through the Nauru civil registry or a diplomatic representative is required.

By Adoption

A child adopted by a Nauruan citizen may acquire citizenship if:

  • The adoption is legally recognized under Nauruan law.
  • The child is a minor.
  • The Cabinet or responsible Minister approves the citizenship grant in connection with the adoption.

By Marriage

A foreign national married to a Nauruan citizen may apply for citizenship after 2 years of residence in Nauru. This is one of the shorter spousal residency requirements in the Pacific region.

Conditions:

  • The marriage must be genuine and subsisting.
  • The applicant must be of good character.
  • Renunciation of prior citizenships is required.
  • Cabinet approval is necessary.

By Naturalization

RequirementDetails
Lawful residenceAs determined by Cabinet; 2 years for spouses of Nauruan citizens
Good characterMust be of good character
LanguageKnowledge of Nauruan or English
Intent to resideMust intend to reside permanently in Nauru
RenunciationMust renounce all prior citizenships
Cabinet approvalRequired for all naturalization grants
FeeAUD 200

Practical note: Naturalization outside of marriage to a Nauruan is extremely rare. The small population and limited economy mean there are very few pathways for foreign nationals to establish the kind of long-term residence that would support a naturalization application.

Loss and Renunciation

Automatic Loss

A naturalized citizen who acquires the citizenship of another country may lose Nauruan citizenship. Citizens by birth enjoy greater protection against automatic loss, though the exact scope depends on the specific provisions applied by Cabinet.

Voluntary Renunciation

A citizen may renounce Nauruan citizenship by declaration, provided:

  • The person holds or is assured citizenship of another country.
  • The person will not be rendered stateless.

Deprivation

The government may deprive a naturalized citizen of citizenship if:

  • It was obtained by fraud or misrepresentation.
  • The person has shown disloyalty to Nauru.
  • The person has been convicted of a serious criminal offense.

Citizens by birth are generally protected from deprivation.

Restoration of Nationality

There is no formal automatic restoration mechanism. Former citizens who wish to regain Nauruan nationality must apply through the naturalization process, subject to Cabinet approval.

Given the very small size of the Nauruan community, former citizens with genuine ties to the island may find a sympathetic reception from the Cabinet, but there is no guaranteed pathway.

Stateless Persons and Foundlings

  • A child found in Nauru whose parents are unknown is presumed to be of Nauruan descent and is treated as a citizen.
  • The Constitution contains general protections against statelessness for persons born on Nauruan territory.
  • Nauru is not a party to the 1954 or 1961 UN Conventions on statelessness.
  • The presence of the Australian-operated Regional Processing Centre (for asylum seekers) on Nauru has created complex questions regarding the nationality status of children born on Nauru to detained asylum seekers. These children do not acquire Nauruan citizenship — they are not of Nauruan descent and no jus soli rule applies.
