Fatboys is who I always see recommend in Bangkok

@Ken ******

that depends on the things I asked in my post. If the agent did things that are impossible for a normal person to do, then you cannot get the next extension yourself because your file has anomalies, like no history of required funds, or receiving your visa/extension before they would normally be allowed. Red flag and you'll be sent away

@Terry **********

you can transfer your yellow book. Much simpler process. Unfortunately I don't know what that process is.

@Amos *********

did you use your own money in the bank or did they agent use their money?

Did you convert to a 90 day non-O inside of Thailand last year and also get the 1-year extension at the same time, so 15 months in total? If you did that and both your non-O visa and 1-year extension have the same date, you won't be able to apply for anything on your own. You'll have to use an agent again next time.

You must use the immigration office that services the province you live in (the district is irrelevant).

When you move, your landlord must file a TM30 within 24 hours of your arrival. The TM30 is what dictates the immigration office that you use.

Funds must be your Thai bank account, in your name only.

Not if you're trying to enter visa exempt. But if you have a valid visa then you can return same day without issue.

I assume you mean Phra Khanong, in Bangkok.

If that's the case, you go to the main immigration office at Chaeng Watthana to apply for your extension based on retirement. You're not getting a 1 year retirement visa, as you already have the retirement visa. You're just applying for an extension.

@Cris *****

it's as fair as life

@Kim ********

there is no number of days to leave. The moment the divorce is final, the extension is invalid. Most people will know ahead of time and plan accordingly.
