Vietnamese nationals can pursue Cambodian citizenship by investment, by a contribution to the Royal Government or a qualifying investment in an approved project. Thresholds have been under review, so the figures must be confirmed before acting.
Information, not advice. Figures are indicative and current as of June 2026. Always confirm the present rules with the official program authority and a licensed professional before you act.
Vietnamese nationals are eligible under the Law on Nationality, which provides for naturalisation by investment or by contribution. Cambodia permits dual citizenship, so a Vietnamese applicant is not required to renounce a prior nationality under Cambodian law. Confirm how your own home country treats dual nationality separately.
Applicants must be adults of good character with a clean record.
The two routes are a cash contribution to the Royal Government, and an investment in a project authorised by the Royal Government or approved by the Council for the Development of Cambodia. Both lead to naturalisation by royal decree once the file is approved.
Reporting suggests the process from a complete application to a passport can run a few months, with only a small number of visits required. Timelines depend on the authority and the route. Confirm current processing windows before you rely on any figure.
Budget for the contribution or qualifying investment, government fees and professional support. The thresholds have reportedly been revised by a recent sub decree, and figures in older guides may no longer apply. Confirm the current figures with the official authority.
| Route | Indicative amount | Notes |
|---|---|---|
| Contribution to the Royal Government | Confirm the current figure with the official authority | Thresholds reportedly revised by recent sub decree |
| Investment in an approved project | Confirm the current figure with the official authority | Project authorised by the government or the Council for the Development of Cambodia |
| Government and processing fees | Confirm the current figure with the official authority | Set by the authority |
