Can I Change My Non-O Visa Based on Marriage to a Non-O Business Visa Without Leaving Thailand?

Another thing worth considering is that if you, for whatever reason, lose your job, you no longer have a valid extension of stay. If you get a work permit on an extension based on marriage, and you stop working, you still have your permission of stay.

@Andrew *****

sounds lik you aren't changing the type of the visa because you're NOT on any visa, you're on a yearly extension of stay from the immigration office :O

All you'd be doing is changing the reason why you're getting an extension

BUT

know that getting an extension based on employment inside the country takes a WHOLE PILE of paperwork from your employer, the shares of the company, who owns what, the taxes, the employment records of the thais that are employed to offset giving you a work permit, your taxes, pay stubs, withholding documents etc.

If you're wanting an easier way to get a yearly extension rather than the marriage extension I think you're sadly confused :/

It is NOT less paperwork nor is it any easier than the marriage extension you're getting now. AND as people pointed out you already can legally hold a work permit and work here on an extension based on marriage.

I just had the same situation reversed and I didn't have to leave the country. I was on Non-B "Work Permit" and I changed it to Non O "Marriage". I did it at Changwattana immigration office

If you are already on extension, it could be done inside the country. But better to check your immigration office if they do and for a handout of requirements.

At least your employer needs to prepare a bunch of papers.

You can apply for an extension when you have 30days or less on your current stamp in most of provinces, some only 15days or less. Check your local immigration office in how many days left they allow you to apply.

If you mean you want to apply 60days extension visiting Thai family, this is also better to check with your local immigration office if you can apply another extension after that 60days.

no problem to change from the Extension to Stay based on being married to a Thai into working inside Thailand.

The reason sounds strange as based on working is at least double the amount of documents needed to apply for an Extension of Stay.

But I guess look at the option to back up your financial statement of being married using your Thai Income and work permit in stead of the income from abroad as you do now

the extra paperwork for a "based on marriage" Non-O has made many change to the much easier Non-O based on being over 50. However if the OP intends to work, he cannot do so with a Non-O based on being over 50, but he can with a Non-O based on marriage plus a work permit

I don't think you want to get rid of your Non-O visa, as much as you want to stop your extension of stay based on marriage and convert it to an extension of stay based on employment. This requires you having a job within Thailand.

Do you currently have a job in Thailand, and is the employer willing to give you the paperwork for an extension of stay? Do you have a work permit?

What’s the reason for the Non B visa?

Are you still married to a Thai?

Do you have a Thai child?
