I have trawled through the past 9 months of posts looking for this question, so please accept apologies if this is a stupid question or a repeat.

I have a Non-Imm B multiple entry visa issued almost three months ago.

Within the next few weeks I will reach the 90 day limit of the "Immigration Permitted to Stay" stamp that my Passport was marked with when I arrived in Thailand.

I have an active WP4 that is also marked with the "valid until date" to match my Passport stamp above.

I understand that to get the "Immigration Permitted to Stay" stamp refreshed for another 90 days ALL I have to do is cross ANY international boarder, and present ONLY my Passport and WP4 ?

Thai immigration look at the Non-Imm B Visa (multiple entry) and stamp me back into Thailand for another 90 Days ????

Is there any need for ANY other paperwork, forms, pictures, proofs of employment, proof of tax payments (I have my Tax card too.) to support my re-entry.

I live between Pattaya and Bangkok so any fly/drive/bus boarder crossing is possible.

Thanks in advance.

You must exit Thailand, enter/exit another country, return to Thailand to obtain a new 90 day permitted to stay stamp and then you must have labor change the work permit to match.

You will require a visa if you enter Cambodia and photos and money will be required. Nothing else but you and passport.

Thank you Lopburi, I saw you were online and hoped that you might pen a reply.

Yes, I have my office run-about ready to go down to CB do do that bit just before I'm "due".

I did Cambodia a few years ago as a tourist, and Laos on a day trip while I was near that crossing on a whim, I'll take a look at the map and maybe choose somewhere I've not seen before.

Thank you for your guidance.

You could try the Ranong casino crossing by land. Or down to Hat Yai/-Sadio or Pedang Malaysia crossing. Or flights to KL/Singapore/Vietnam/Hong Kong/China.
