Alibhai . . You need the up-to-date valid TM30 registration at your accommodation, or Immigration will not service your request for a "change of visa type" from the visa-exempt entry to the initial 90-days Non-Imm-O Retirement Visa.
So first things first – tell your landlord you have been TM30 registered in a hotel yesterday, and returned to your premises today. So your landlord IS OBLIGED to file a new TM30, and “export” it (download after submitting and print)
FIRST the problem with your landlord needs to get solved.
For the application to the "change"you need a minimum of 15 days left on your "admitted until" stamp.
***(You DO NOT HAVE A TOURIST VISA, you just have been admitted for a 60 days stay permit)
You seemingly have the required funds of 800,000 THB in your Thai bank account (from your previous Retirement Extension of Stay)
so the only problem is that Immigration needs your rental contract, and a submitted TM30, and your updated bankbook showing the 800,000 THB sitting in your account (they might ask for a letter from the bank, though)
***you apply for the “change”, the fee is 2000 THB. The 90-days visa will be issued for “15 days under consideration”
***as soon as 30 days are left from the 90 days, you can apply for the wrongly called so “retirement visa” - which is NOT A VISA at all.
It just is a “1-year extended stay permit based on retirement” and you need a letter proof from your bank that the 800,000 THB have “seasoned” in your Thai bank account by 2 months. The fee for the Extension application is 1900 THB
*** Then you are back to square one, got a “1-year retirement extension” stamped, and you should ALWAYS immediately right after having been issued the extension stamp, buy a single re-entry permit for the 1-year extended stay permit, so it doesn’t become invalid should you exit Thailand
