American nationals can pursue Cambodian citizenship through investment under the Law on Nationality. Reforms reported to take effect in December 2025 raised the qualifying amounts substantially, so older figures should not be relied on.
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.
Cambodian law does not bar American applicants. Citizenship by investment runs through the naturalisation provisions of the Law on Nationality, which is granted at the discretion of the government rather than as an automatic purchase.
Cambodia permits dual citizenship, and the United States allows its citizens to hold another nationality, so an American can in principle add Cambodian citizenship. United States citizens remain subject to US tax and reporting. Confirm your position with a licensed professional.
The investment paths reported after the 2025 reforms are a qualifying investment in approved priority sectors, reported at a minimum of 1 million US dollars, or a donation to the national budget, reported at 3 million US dollars. Earlier, much lower figures are no longer current.
These are discretionary naturalisation routes, not a streamlined programme with a published guarantee of approval. Confirm the current routes and figures with the official authority.
Because citizenship is granted by Royal Decree on official recommendation, timing is less predictable than in the structured Caribbean programmes. Plan for a process measured in months and subject to government discretion.
Confirm current processing expectations with the official authority before committing funds.
The dominant figure is the qualifying investment or donation. On top of that sit official fees and your own professional costs. The investment route is intended to be deployed in approved sectors, while the donation route is not returnable.
Given the scale of the recent changes, treat any older quoted figure with caution and confirm the current amounts with the official authority.
