Hi, any advice would be greatly appreciated. I am returning to Thailand next month with my old ( now cancelled ) UK passport which contains my Retirement extension until Jan 2027 and re-entry stamps. Also have my brand new freshly issued UK passport. Anyone done this before or experienced any issues with gaining entry at Savarnabhumi immigration with the Retirement extension in the old passport ? Thanks

Bring both with you. This is AI and valid........When entering Thailand, you must present both your new passport and your old passport (which contains the valid retirement visa/extension stamp), along with a valid re-entry permit if required. The immigration officer will inspect both documents to link your active status and place your new arrival stamp into your new passport.

Required Documents at Airport Immigration

• New Passport: Your current, valid travel document used for entry.

• Old Passport: The canceled or expired passport holding the valid retirement extension sticker or visa.

• Re-Entry Permit: Either stamped in your old passport (obtained before leaving Thailand) or processed on the spot if available, though leaving with a pre-arranged re-entry permit is standard protocol.

• Next Steps After Arrival

  • Local Immigration Office: Visit your local Immigration Bureau office soon after arrival to formally transfer your visa history and stamps from the old passport into the new one

No problem.

You will need to present both old + new pp to airline for boarding pass and immigration in Thailand.

Which immigration office do you deal with.

While there is no urgency to attend immigration office to transfer stamps and visa info, it's good idea to do that.

Don't forget to update your new pp # etc with your Thai bank.

Personally I don't worry about updating details on TDL.

If you use banking app you should update with telco.

Provide both passports at UK departures desk.
Provide both passports at Immigration arrivals.

Entry stamp will be stamped in new passport.

Thereafter go to your local IO to have stamps transferred to new passport.

Thanks to all who replied - put my mind at rest 👍

Be prepared to pay 500 Baht for the service of transferring the stamps.

(the extension in the old passport is of little/no relevance - the re-entry permit is. That will get you stamped in until the extension expiry date)

Think you will find it's the other way around.

It's necessary to transfer extension stamp and Non O details to new pp.

Some folk do not bother to transfer the reentry permit and just travel abroad with both passports.

One reason being is that the immigration office will not transfer the reentry stamp if the permit was not issued at the imm office.

This happens when permit issued at airport.

A little off topic but may help someone. I recently did my extension with my new passport (already transferred the extension stamp to new one), They needed my old passport as well, showing my original Non O

Not surprising however the information of original Non O visa is noted in new pp when you did the transfer of stamps so don't see the point of them requiring both.

Just a follow up point. On the TDAC do i enter the NEW pp number and the visa number from the expired pp ? Thx

Enter the new passport number.

The visa number is not a compulsory field to complete, just leave it blank.

I’m glad I found this topic given I’m in exactly the same position! Due to arrive on 1 September with visa due for extension on 6 September- so hoping no issues with my Qatar flight given the war! Fingers crossed 🤞! 😱 A small window but will be fine barring any major disruption. Dial it down boys (Trump and Iran) during that time please! 😜

Never thought about that. Perhaps cause I'm Oz.

If your end up with issues and end need start over..

Your existing funds in Thai bank account would not require proof for abroad.

You could either apply for non O eVisa or enter visa exempt and obtain Non O in Thailand.

Inconvenient but possible.
