Cambodia permits dual nationality, which sets it apart from several of its neighbours and matters a great deal to a diaspora largely formed by people who left in the 1970s and 1980s and naturalised elsewhere. Citizenship passes by descent from a Cambodian parent, and the practical question is documentation rather than entitlement.
Quick facts
Many Cambodian-American families lost their documents entirely during the upheavals of the 1970s, and reconstructing a civil record is often the real work. The embassy’s birth certificate request service is the usual starting point.
The sequence
| Step | What it produces | Where |
|---|---|---|
| Certified birth certificate request | Cambodian birth certificate | Issued in Cambodia |
| Identification documents | Cambodian identity card | In Cambodia |
| Passport application | Cambodian passport | Embassy in Washington |
| Visa for people of Khmer origin | Entry without full documentation | Ask the embassy |
| Reconstructing lost records | Depends on the case | Legal advice in Cambodia |
Where the documentary chain cannot be completed, the visa category for people of Khmer origin is the practical alternative: it lets families visit and maintain a connection while the civil record is sorted out, or instead of sorting it out at all.
How to proceed
- Establish what documents the Cambodian parent still holds.
- Request the certified Cambodian birth certificate through the embassy.
- Take advice in Cambodia where records were lost or destroyed.
- Obtain Cambodian identification once the civil record exists.
- Apply for the passport at the embassy.
- Where the chain cannot be completed, ask about the Khmer-origin visa category.
Required documents
- Cambodian parent’s passport or identity card, with the name in Khmer.
- Your own U.S. birth certificate.
- Parents’ marriage certificate where applicable.
- Any surviving Cambodian civil documents.
- Completed request forms with valid contact details.
- Money order or cashier’s check for the fees.
Where to apply
At the Royal Embassy of Cambodia in Washington; civil records themselves are issued in Cambodia.
Additional notes
Start with what the parent holds
An identity card or passport showing the name in Khmer is usually the anchor for the whole file. Find it before anything else.
Lost records are common
Given the country’s history, missing civil documentation is the norm rather than the exception, and a lawyer in Cambodia is better placed than a consular counter to advise on reconstruction.
The visa is a real alternative
Not every family needs to complete the citizenship chain. For visiting relatives and property matters, the Khmer-origin category may be enough.
Children
A child’s file follows the parent’s documented status, so establishing the parent’s record first is the efficient order.
