VietnamWhy check first?
When you acquire another citizenship, your current country of nationality may treat it as automatic loss of nationality, or require you to declare it. So it isn’t enough that the new country accepts dual nationality.
Three things to check
- Whether the new country allows other nationalities (Caribbean countries generally do).
- How your current country treats acquiring a foreign nationality.
- If you hold several statuses (e.g. Hong Kong permanent residence and another passport), whether any conflict.
Common situations
| Situation | Nationality question |
|---|---|
| Residence or permanent residence | Generally no change of nationality |
| Citizenship by investment (Turkey, Caribbean) | Usually allows dual nationality; check your current country |
| Naturalising after residence (US, Canada, Australia) | Residence first; nationality arises at citizenship |
| Naturalising in Japan | Japan generally does not recognise dual nationality |
Planning advice
- List every family member’s documents and statuses.
- Have your consultant and a lawyer assess them together.
- Consider your children’s future nationality.
- Make sure a new status doesn’t affect an existing one.
