DSI moves to revoke Israeli businessman's Thai citizenship over unrenounced original nationality

The Department of Special Investigation (DSI) has formally recommended revoking the Thai citizenship of an Israeli businessman. According to a report by The Standard (in Thai), the move comes after authorities discovered the man had held Thai citizenship for an extended period without renouncing his original nationality.

Thailand's Nationality Act generally requires foreigners who naturalize as Thai citizens to renounce their previous citizenship. However, enforcement of this rule has historically been inconsistent, leaving many naturalized expats in a grey area regarding their dual-nationality status.

The DSI's recommendation to the Department of Provincial Administration signals a potential shift toward stricter enforcement of naturalization conditions.

What this means for you

If you are a naturalized Thai citizen or are currently in the process of applying for Thai citizenship, this case warrants close attention.

• Review your naturalization terms: Check the specific conditions under which your Thai citizenship was granted. If renunciation of your original nationality was a stipulated requirement, failing to do so carries tangible risks.
• Distinguish between naturalization and birthright: This enforcement action targets a naturalized citizen. Thailand generally tolerates dual citizenship for those who acquire it by birth (for example, children born to one Thai and one foreign parent).
• Expect heightened scrutiny: While this is currently a single high-profile case, the involvement of the DSI suggests authorities have the mechanisms and willingness to audit historical citizenship files.

It is important to note that the DSI has only proposed the revocation; the final decision rests with the Department of Provincial Administration and the Ministry of Interior. We will monitor this case to see if it develops into a broader audit of naturalized citizens in Thailand.
