What are the requirements and process for obtaining a retirement visa in Thailand while on a 60-day tourist visa?

Vincent, Okay, lets sort this out. First there is NO such thing as a retirement visa! Even though it is called that by every Tom Dick & Somchai (foreigner and immigration officer alike) there is NO such thing, period. 　

You can go from a 30 day visa exempt stamp to a 90 day Non-O visa based on being over 50 inside the country at the immigration office by supplying the documentation and using form TM.87 <- application for a visa.

OR

you can go from a 60 day tourist visa entry to a 90 day Non-O based on being over 50 inside the country at the immigration office with the documentation and by using form TM.86 <- change of visa

You turn in your documentation, your proof of financials (there is NO seasoning requirement for using banked money when doing this) and the application will go "under-consideration" for 14 days when you go back and get the 90 day Non-O stamped in your passport along with a 90 day admitted until stamp.

THEN you wait until you have 45 days or less left on that stamp (and until your money is seasoned the requisite 60 days required and you apply for a yearly extension of stay based on being over 50.

The ONLY place the word retirement appears is in the english stamp they put on the yearly extension.

To Get a retirement visa You have to have a Non 'O' visa first I thought! so you cannot convert a tourist visa into a Retirement visa because you need 2 moths remaining on you current visa ... . that is what I thought !

FWIW: the thai immigration office in Jomtien cannot issued 90 day Non-O visas anymore. So if you're comin' in on a 30 day visa exempt entry or a 60 day tourist visa and wanna get a 90 day Non-O issued in country you do it in Bangkok.

Must be over 50 years of age.a o.a visa is a better visa obtained from your home country.gives u 2 years

Marry a thai lady lol

Multiple entry visa 6 months + 2 then extend 30 days will give you 9 months

I must be missing something, wasn't it 800,000 baht ?

Yes, you can. But if you go the 800,000 in the bank route It has to be in the bank untouched for three months. Or if you have a retirement income of 65,000 per month, that is acceptable. You would go to Immigration and apply to change your visa type to O, and at the same time extend it for one year based on retirement. You do not mention where you would be doing this BKK or another province, that is important as each area seems to have its own little 'quirks and foibles'.
