Have your partner write a letter signed by the company boss explicitly giving you permission to work remotely from Thailand. It would also be worth including that you will not work with any thai clients or entities

@NeL ****

if you try to extend at an immigration office they will, at the border they won't

You can't get a marriage visa if you don't live together. They can visit your home to check and also require witnesses to speak to the fact you both live there together.

You find an option you want to apply for, you make sure they are approved for the DTV program, you pay them for a minimum of 6 months (preferably a bit longer), they supply you with paperwork and you use that to justify your application.

Even 6 months might not be enough depending where you apply. I'd suggest a little over 6 months

@Clarence ********

so you can apply for a 90 day Non-O in your home country using your pension income but to get a 12 month extension of stay inside Thailand after arrival you will need to put 800k baht minimum in a Thai bank account. If you build up 12 months of transfers from overseas of a minimum of 65k baht per month you can use that for the 2nd extension onwards

@Clarence ********

looks like you are Canadian? If so your embassy has stopped providing income certificates. So if you are already inside Thailand on an extension of stay and can show a minimum of 65k baht per month transfers for the past 12 months you can use this to apply for the next extension. But you can't use this method to apply for a 90 day Non-O visa nor the 1st extension from that visa

If you already have a Thai bank account you can come in visa exempt, but if you don't you will have difficulty opening one on that so get the Non-O before you come

Are you actually on a Non-B visa or on an extension of stay? Look in your passport. If you are actually on a visa you need to wait for it to expire, you can't cancel it and you can't simultaneously hold 2 visas. If you are on an extension of stay you should cancel your work permit then take the document showing you've cancelled your work permit to immigration to cancel your extension of stay, then go apply for the DTV

@Anzaar *****

you are aware that your dependants have to also be outside Thailand when they apply for their DTVs?
