How can I transfer my visa to my new passport and extend my visa in Thailand?

glad that worked out for you.

@Joseph *******

no, nothing to do which visa you have or use. It is a standard Immigration requirement.

I do think being on o-visas for such a long time now works in your favour sure if I was on tourist visa may have been a different story but you got to get lucky sometimes

@Joseph *******

you were lucky to get away without letter.

There very good at Mukdahan they use a bit of common sense there I was annoyed with embassy for misinformation

@Joseph *******

quite lucky, I have seen immigration offices send people back to the consulate to get the letter before they'd transfer the stamps.

They did ask for receipt of new passport which I did not have due to misinformation from Australian embassy

Transfered old passport number and visa details and tak re-entry stamp into new passport before I crossed from Mukdahan

@Jos***

, what were you "transferring" ?

They never transfer visas to a new passport, only extensions of stays and re-entry permits.

@Tod ********

thank you!

@Dori ******

if you are on a valid multi-entry VISA (not an extension of stay) you have to travel with BOTH passports until the visa in the old passport runs out. All they can do is stamp you in and out on the new passport.

What if you are on a multiple entry visa and there is 4 month left on it.. can they transfer that too or would I loose some month. I am due to get a new passport in November.

I just did my transfer at a border crossing only had old passport and new one had no letters from embassy had no problems

Julia this is commonly called a "visa transfer" but technically it may be more properly called a "permission to stay transfer". It's the same thing your embassy is referring to as a "visa transfer".

The point is you need to just bring both passports to immigration and they transfer your existing permission to stay, plus put a stamp in your new passport with details from your old passport. They need this letter now also, they didn't when I last did it in 2014 but they do now.

You can do an extension immediately after the transfer. I can't remember if I was able to put in the forms for both at the same time, or whether I had to do them sequentially (i.e. wait for the passport with the transferred stamp back), Tod might know. But I did both in the same visit.

@Ju***

When I got my new Passport, the embassy gave me back my old, devaluated Passport (apart from those pages who still had a valid visa in it, like my Thai Non-b and my USA) and some letter I did not specifically asked for.

On my next Visa visa run a few weeks later, I gave Immigration in Sadao both my Passports and that letter. The officer passed my documents to a girl in the next boot who put a transfer stamp on the first page of it

Only problem I had, after the girl stamped my passport I was of to Malaysia only to be sent back as she didn't stamp me out of the country.

No Chance. 25km in 34 min. This is Bangkok.

Maybe 1hr is a good time.

I have no idea about distance and traffic jams in Bangkok, I'm living about 800 Km south of it, nice and quiet.

It is not possible to transfer the Visa sticker from your old passport to a new passport without damaging the old one and use glue or staples to attach it into the new one. Immigration will put a new admitted to stay stamp into your new passport with your original date or if you directly apply for an Extension of Stay with a new date. The visa sticker is used and does not have any benefit anymore.
