The Thai Embassy in Tokyo will only issue me a tourist visa (not an non-im O)

I have enough funds in a Thai bank to meet the 1 year retirement requirement and am 57 years old

Will any immigration office convert a Tourist visa to a non-im O and then extend it for 1 year or is it done only in Bangkok ?

Thanks

Not all will do and in that case you can use Bangkok for the conversion and then return to normal office for the extension of stay.

What Thai immigration office do you plan to use for your retirement extension? With that information, someone here may be able to tell you whether that office will also do the first step, the change of visa status from tourist to O.

I plan to settle in Khun Han which is in the SIsaket Province of Isaan

Looks like Phu Sing is the immigration office covering that area

What is needed for the conversion ?

Another newbie question

Where can I find the information of where is the Bangkok immigration office located ?

choose Ciang Wattana office.

Proof of meeting extension of stay other than financial seasoning requirement. So bank account with 800k or embassy letter of 65k monthly income or combination plus passport/form for conversion (varies by type of entry)/fee 2,000 baht/4x6cm photos/evidence of residence. For bank account both passbook and copies plus letter from branch manager of account balance. Upcountry two or three copies of everything will be required but for Bangkok only one copy.
