OP : thank u for your helpful post re retirement extension at Jomtien.
One matter:
"While very minor for me today as no queues anywhere, this TM 30 issue could have added 1-2 hours to my day. A bit ridiculous they don't accept the very formal looking TM30 online receipt that has immigration logo's all over it (but accept a scrappy tear off handwritten page instead)."
I have the same formal document confirming TM 30 from Immigration online receipt with the immigration logo on it but not the scrappy tear off document.
The formal document was given to me by the Landlords agent and when I recently did my 90 days online they had registered my new address without any need to go to immigration.
However, it seems from what you are saying when doing the retirement extension, they expect the tear off slip to be provided.
Is that right?
