Can my husband work in Thailand on a Non-B visa as a Japanese national if he is registered as Thai?

Hi, my husband is half Thai and half Japanese, and we are considering moving to Thailand for work.

However, we have some concerns regarding military conscription. He was registered in a Thai Tabien Baan at birth and was assigned a Thai national ID number, but he has never had a physical Thai ID card issued.

Because he would like to avoid potential military service obligations, we were considering having him work in Thailand as a Japanese national instead, meaning he would apply for a Non-B visa and work permit as a Japanese citizen. Is that even possible given that he is already registered as a Thai national in Thailand?

We also considered renouncing his Thai nationality, but from what we understand, the renunciation process requires documents such as SorDor.35 and SorDor.1 / SorDor.8 / SorDor.9. Neither he nor his relatives have ever received any of these documents.

In this situation:

* Could he face legal or administrative issues if he tries to work in Thailand?

* Is it possible for him to obtain a Non-B visa and work permit as a Japanese national despite his Thai registration?

* If we want to clarify his status properly and resolve any outstanding issues, which authority should we contact (e.g., district office, military office, embassy, etc.)?

We would greatly appreciate any guidance.

<Additional note>

Some people keep telling him to “man up” or “serve properly,” but please understand that he did not consciously choose to keep Thai citizenship. His family did not complete the necessary procedures to renounce it at the appropriate time, and that is why we are facing this situation now.

He has made the decision to live his life as a Japanese citizen, not as a Thai citizen, and he is trying to follow the proper legal procedures so he can work as a Japanese national. Please stop attacking him.
