I saw Siam legal said its 6 trips on holiday, I doubt it will affect to many people.

The enforcement by thai immigration is denying visa exempt more than 2 times if its back to back, on the 2nd one you can only extend it by 7 days. Enough time to get out the coutry. You can come many times if you travel back to your country and have some space between trips. You must look like a tourist with hotel booking, flight out etc

@David ********

the OA retirement visa needs health insurance, the non o over 50 does not

If you came from your home country each time it seems ok, its a border bounce or quick return there wanting to limit.

If your wanting a OA retirement visa its best to obtain a health insure on the approved list.

yes, but its unlikly to be a problem because he only stayed in Thailand while getting his flight.

Yes, you take your baggage and recheck with local airline on separate ticket to Cambodia.

Yes, you go through immigration in BKK both times.

Yes, you can use the visa exemption again upon return to Thailand from Cambodia if eligible and within limits.

No METV is strictly required unless you want multiple entries guaranteed without border entry limits.

The 30 day extension is done at your closet immigration department 30 days before the orignal expires

There is a Facebook group for Thai citizenship group might worth looking at that
