Is it possible to change from a Non-B visa to a Non-O visa based on child custody while retaining my work permit in Thailand?

@Arn ********

first off your current extension is good until Sept 24th 2021. Secondly the immigration office doesn't issue work permits so you shouldn't even be talking to them about it at all period. They issue visas and extensions of stays. The Ministry of Labour issues work permits so they are who you need to talk to.

And lastly, you're NOT switching to any "visa" you're changing the reason for your extension from employment to one based on raising half thai children that you have legal parental rights to. People do that all the time. When this current extension starts to run out (in Phuket you can apply for a new extension when you have 45 days or less left on your current stamp) you will go in and apply for a new yearly extension based on raising half thai children by having the 400K baht in a thai bank account in your name only.

You can hold work permit with Non-O raising half Thai child. But if you can change the reason of extension to that depends on your local immigration office. If your local immigratioin office says they don't issue in-country non-O visa nor allow to change the reason of extension to that, you may not be able to change your extension from employment to raising hald Thai child based. If local immigration office allows and you can meet all requirement, you can change the reason.

By non-o child custody, is this an one year extension of stay based on raising half Thai child? If you meet the requirements for this extension of stay, then you can continue holding your work permit
