You go to the counter that issued your son's extension at Chaengwattana. Bring both passports, TM30, and the embassy letter if your embassy still issues one. The Immigration Office would know which embassies are still issuing and which are not.

You cannot make an appointment to transfer stamps.

, you can apply for in-country Non-O visa when you enter on visa-exempt, not only on tourist visa.

Now you are on no visa at all. You have to apply for an in-country Non-O retirement visa first when you still have 15 days (calendar days or business days depending on provinces) or more.

You will have an under-review period of around 2 weeks. At the end of that under-review period you will get an in-country Non-O visa with 90-day stay stamps inked into your passport.

When your stay is around 30 days or less, you can finally apply for a 1-year extension based on retirement.

Go to the local immigration office for the requirements handout for an initial visa and extension.

Attached is the rough timeline for in-country visa application procedures.

, thanks, it's Phuket specific requirement as police order has not been changed.

@Robert ********

, if the child is foreigner without Thai ID, it's 500K baht. 400K baht of funds is for Non-O dependent on Thai (or sometime said a Half Thai) child.

For 1-year extension based on supporting a foreign child (Guardian), you need to have 500K baht in your account (800K is for a retirement visa/extension).

The general rule is, you must have 500K baht in your account for 30 days before your first application for a 1-year extension from Non-O visa 90 days stamp.

Then, you have to keep 500K baht in your Thai bank account for 3 months for every subsequent yearly extension application.

, you can check their website

@Adrian *****

, he canceled his previous and existing extension after re-enter Thailand on another status. Not the same procedure as when you cancel an extension that you are on currently

Thank you for the update. Glad you sort things out smoothly.
