You can only get one 30 days extension on one 60 days tourist entry. (Tourist visa/visa exemption).

You apply on a TM.7 form at the immigration. Normally you’ll need a receipt of your TM.30 address registration privat or hotell. You’ll need a pass photo, copy if ID-page and latest stamp in your passport and 1900 baht in cash.

Yes you can just leave 24K or 12K USD (retirement/marriage) in a Thai bank as a guarantee and "forget" it, and that’s it.

But you don’t have to save anything if you don’t want to. The requirements are just minimum income for life expenses every month. (From the second year).

@Stephen ******

As Brandon also explains, you have two options;

Apply for a regular Non O based in retirement. The requirements are income 65K baht or funds equal to 800K baht. You’ll need to bank 800K baht for your first year in Thailand. For your second year you can use twelve monthly transfer of min 65K baht a month.

Or

Apply for a Non O based on being married to a Thai. The requirements are income 40K baht a month or 400K baht. For the first year you’ll need to bank 400K baht in Thailand. For the second year they might accept monthly transfer of min 40K baht a month which not all immigrations do. Then you’ll need 400K baht every year.

So if you fulfill the requirement for a regular Non O and yearly extensions of stay based just on retirement, it’s the best and easiest route.

You can apply for a 90 days Non O visa based on being married to a Thai through your embassy at home with your income. Doesn’t have to be a pension.

For your first year extension of stay in Thailand you’ll need to bank 400K baht in a Thai bank two months prior to your extension. If you do twelve consecutive transfers of min 40K baht a month to your Thai bank it might be accepted as proof of income. If your immigration don’t want to accept it, you’ll need to bank 400K baht two months prior to your extension each year.

You can only apply for a METV at your registered permanent residence at date. Safest option now is a landborder transport company. They won’t bring you unless they’re confident in getting you another visa exemption. Arrange tours every morning.

You can’t get a six months visa inside Thailand. Soft power options for a DTV is an option but it’s a five years visa and also have to be applied for outside Thailand. Personally I would just have used a professional transport company to bounce me out and back for another or maybe two more visa exemptions.

@Jovan ******

Haven’t seen it mentioned among the 45 days immigrations (not among the 7 days either😉) so my best guess is that Hua Hin is one of the 30 days immigrations and as I can remember it’s also previously confirmed.

You can apply for an extension of your visa exemption. Most immigrations accept extension 30 days before your current stay expires, some as Jomtien and Samui only within the last week. Bangkok and Chiang Mai accept 45 days before.

Up to the IO you’re standing in front of as Phil said, but you could easily cover your stay without any risk with a six months multiple entries turist visa applied for online through the Thai embassy that serves your area before you leave.
