Can I get a 30-day extension on my 90-day Non-O visa in Thailand?

Ask in Imigration if you apply for extension based on thai child do not need money to stay for two mounts. For retirement and thai wife need 2 mounts. First speak with them. Can ask also same agent can help you.

By the way I do miss my time with BSB . I was one of the orange army for two years .

I would ask your immigration office first maybe they are fine with the time . Especially if you have paying more into the account as well

All great feedback! I had to do an extension for the exact same reason. I was able to get a 60 extension because my wife is a Thai citizen…. Otherwise you will need to exit and wait till your funds mature!

There is no 30 day extension available on that visa. If you have immediate Thai family you can get a 60 day "visit Thai family extension but other than that it's only a 12 month extension. Sounds like you will have to exit Thailand and either apply for another 90 day Non-O visa at a nearby consulate or come back in visa exempt and apply for it at your local immigration office if they issue them (most do but not all)

I'm confused. Didn't you have 90 days already 🤔

for the "change of visa type", you need a proof that the funds came from abroad. You need a rental contract, and you need a minimum of 15 workdays left on your entry stamp, in order to be able to apply. Your case is number 9 on this .pdf list of requirements to the "change of visa type" on the website of Thai Immigration, however I would visit "your" Immigration and ask them for THEIR list, as it could differ a little bit from the official one . . .open this link, change the language to English and dowload number 9

If you have Thai family here can get 2 months extension

no, you cannot get a 30-days extension on top of the 90-days stay permit you received when you entered on a Non-Imm-O visa. Unfortunately, you will have to exit Thailand before the 90 days are up. You have the option of remaining in a neighbour country until your funds have seasoned for the required 2 months, then re-enter visa-exempt, get stamped in for 60 days, visit Immigration and apply for the "change of visa type" from the exempt-entry to an initial 90-days Non-Imm-O Retirement Visa. It will count from the day you apply. And as soon as 30 days left on these 90 days, you can apply for the 1-year Extension of the Stay Permit Based on Retirement with the funds in the bank, and the bank letter confirming the seasoning

The only extension is the 12 month extension of stay, so unless anyone can think of a better way you will have to get another non-O.
