Not quite, but the Immigration Bureau tries to make you believe that it is so with a page on their website.

The TM.30 notification that was made for your arrival is obviously registered in immigration's database but for some unfathomable reason some, if not all, immigration offices ask for a new copy of that TM.30 notification with ever application of extension of stay. However, you mention "a new TM-30 receipt". Are you saying that the immigration office wants a new TM.30 notification to be made and wants a copy of the receipt for that new notification? That would be weird.

No chance at all, in my opinion. With all other visas and and with extensions of stay, immigration regulations clearly spell out that the relationship has to be de jure, ie legally registered, and I see no reason why embassies and consulates would not apply this to the DTV, but it will do no harm if you inquire at the Thai embassy in France about this.

Last words from the OP.

Not related to Thailand.

Is this fine official, ie does immigration give a receipt for it?

As the owner of a house, you can legally rent it out without losing your retirement extension.

There are no questions about by immigration when leaving Thailand.

Thank you, @BrandonJT Interesting and yes, confusing. The answer to the questions of @changthenomad lies in the bottom line of the infographic: contact the immigration office.

I don't know what your "2.3/3 year course" is. You can leave Thailand any time without a re-entry permit and then enter Thailand visa-exempt if you qualify for it or with a visa of any type. What is the Non Ed Plus visa you are talking about?

There are two reports in another topic, now closed, about lightening-fast approvals of 90-day reports:

There is already the pinned topic Thai immigration online 90 day reporting system. Therefore, let us post our experiences with the use of this system in that topic, including the positive news about lightning-fast approvals.
