Dual Citizenship

Papua New Guinea does not permit dual citizenship. The Constitution, adopted at independence in 1975, explicitly prohibits holding PNG citizenship alongside any other nationality.

Key provisions:

  • Section 64 of the Constitution states that a person who has a real foreign citizenship and who has reached the age of 19 years is not a citizen of Papua New Guinea.
  • A PNG citizen who voluntarily acquires the citizenship of another country ceases to be a citizen of Papua New Guinea.
  • The prohibition applies to all citizens, whether by birth, descent, or naturalization.
  • Children with dual nationality through birth (e.g., born to a PNG parent and a parent from a country with automatic jus sanguinis) are given until age 19 to choose. They must renounce the foreign citizenship by that age or lose PNG citizenship.

The age-19 rule: This is one of the most distinctive features of PNG citizenship law. Unlike many countries that require a choice at 18 or 21, PNG sets the cutoff at 19. The Advisory Committee on Citizenship oversees compliance. In practice, enforcement can be inconsistent given the administrative challenges in a country of nearly 900 distinct languages and extremely varied levels of government reach across its territory.

Reform discussions: There have been periodic calls to amend the Constitution to allow dual citizenship, particularly from the PNG diaspora in Australia. A Constitutional and Law Reform Commission report in 2019 recommended considering dual citizenship. No amendment has been enacted as of 2026.

Acquisition of Nationality

By Birth

A person born in Papua New Guinea acquires citizenship if:

  • At least one parent or grandparent was born in Papua New Guinea, OR
  • At least one parent is a citizen of PNG at the time of the birth.

Key notes:

  • There is no unconditional jus soli. Birth on PNG territory alone does not confer citizenship if neither parent nor grandparent has the requisite connection.
  • The grandparent provision is broader than many countries and reflects PNG’s approach at independence (1975), when citizenship was defined partly by connection to the territory across generations.

By Descent

A person born outside Papua New Guinea acquires citizenship by descent if at least one parent is a PNG citizen at the time of the birth.

Conditions:

  • The birth must be registered with PNG authorities (Immigration and Citizenship Service Authority or a PNG diplomatic mission).
  • The dual-citizenship prohibition means that a child born abroad who also acquires the foreign country’s citizenship must choose by age 19.

By Adoption

A child adopted by a PNG citizen may acquire citizenship, provided:

  • The adoption is recognized under PNG law (Adoption of Children Act).
  • The child is a minor at the time of adoption.
  • Customary adoption is practiced widely in PNG, but formal legal recognition through the courts is required for citizenship purposes.

By Marriage

Marriage to a PNG citizen does not automatically confer citizenship. A foreign spouse may apply for naturalization, but must meet the full 8-year residency requirement. There is no spousal reduction in the residency period.

Practical note: The foreign spouse must also renounce all other citizenships before naturalization can be granted.

By Naturalization

RequirementDetails
Lawful residence8 years cumulative, including the 12 months immediately preceding the application

Cultural knowledgeAdequate knowledge of the customs, cultures, and society of PNG

Ministerial approvalFinal decision rests with the Minister for Immigration
FeePGK 500

Investment note: PNG does not offer a citizenship-by-investment program. However, foreign nationals who establish businesses and reside in PNG for the required period may qualify for naturalization through the standard pathway. The extractive industries (mining, oil, gas, logging) bring many long-term foreign residents, some of whom have eventually naturalized.

Loss and Renunciation

Automatic Loss

A PNG citizen who voluntarily acquires the citizenship of another country ceases to be a citizen of Papua New Guinea. This loss is automatic and constitutional.

For persons with dual nationality at birth (through no voluntary act of their own), citizenship is retained until age 19, at which point the foreign citizenship must be renounced or PNG citizenship is forfeited.

Voluntary Renunciation

A citizen may renounce PNG citizenship by written declaration, provided:

  • The person holds or has been assured citizenship of another country.
  • The person is of full legal age and capacity.
  • The person will not be rendered stateless.

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 Papua New Guinea.
  • The person has been sentenced to imprisonment for more than 1 year within 10 years of naturalization.

Citizens by birth or descent are generally protected from deprivation, except through the automatic loss provisions regarding dual nationality.

Restoration of Nationality

A former PNG citizen who lost citizenship by acquiring another nationality may apply for re-naturalization. The process requires:

  • Renunciation of the foreign citizenship.
  • Meeting the standard naturalization requirements, including the 8-year residency period.
  • Approval by the Citizenship Advisory Committee and the Minister.

There is no automatic or facilitated restoration pathway. Former citizens must go through the full process, which is one of the longer naturalization timelines in the Pacific region.

Stateless Persons and Foundlings

  • A child found in Papua New Guinea whose parents are unknown is presumed to be a citizen of Papua New Guinea.
  • The Constitution contains provisions to prevent statelessness among persons born on PNG territory who would otherwise have no nationality.
  • PNG is not a party to the 1954 or 1961 UN Conventions on statelessness.
  • The complex ethnic and linguistic landscape (over 850 languages across hundreds of distinct cultural groups) means that customary identification and clan membership often carry more practical significance than formal citizenship documentation in rural areas.
