Papua New Guinea historically did not permit dual citizenship, and that changed: constitutional amendments opened it up in defined circumstances, with the detail administered by the Immigration and Citizenship Authority. Because the position moved, guidance written earlier may be wrong, and the arrangements are not identical for every other nationality.
Quick facts
That makes this one of the pages where a directory can honestly tell you the shape of the question but not the answer to yours. The consequential decision — whether taking American citizenship affects your Papua New Guinean status — should be checked with the authority before you act, not afterwards.
What to establish
| Question | Why it matters | Where to ask |
|---|---|---|
| Does dual citizenship apply to your case? | Conditions are defined, not general | The authority or the embassy |
| Effect of naturalising in the U.S. | May affect your status | Ask before acting |
| Children born abroad | Documented through the parents | The embassy |
| Evidence of citizenship | Records may be hard to obtain | See the civil records page |
| Customary land rights | Tied to citizenship and clan | A lawyer in PNG |
That last row matters more in Papua New Guinea than almost anywhere: the overwhelming majority of land is held under customary tenure by clans rather than individuals, and rights to it are bound up with citizenship and kinship rather than with a title deed.
What to do
- Ask the authority or the embassy how the current rules apply to your situation.
- Do that before taking another citizenship, not after.
- Gather whatever evidence of citizenship the family holds.
- Take advice locally on any land or inheritance question.
- Establish the children’s position alongside your own.
- Keep the passport current once your status is clear.
Required documents
- Papua New Guinean passport or birth certificate.
- Parents’ documents where the claim is by descent.
- U.S. naturalisation certificate where applicable.
- Marriage certificates covering name changes.
- Any earlier Papua New Guinean documents.
- Completed forms and photographs.
Where to apply
Through the embassy in Washington or the consulate general in Los Angeles; decisions rest with the authority in Port Moresby.

Additional notes
Check the date on anything you read
The rules changed, so older articles describing an absolute prohibition no longer reflect the position.
Ask first, act second
It is a short email or call, and it is far easier than reversing a decision about nationality.
Customary land
Most land in Papua New Guinea is held by clans under customary tenure. Any plan involving it needs local legal advice, not a general guide.
Children
Their position follows the parents’ documented status, so sort that first.
