ORIGINAL POSTER

I have owned a property in Thailand for 15 years, where I propose staying, and have recently applied for a Non O , single entry 90 day visa, in order to apply for a Retirement Visa.

The Embassy is asking for additional paperwork, a Note Verbale or an Invitation letter, can anyone please explain where an invitation letter comes from?

Whoever owns your house in Thailand can write a letter advising they have invited you to stay at your house. I know it sounds stupid but have done these in the past, my Thai wife inviting me to stay at our house in Thailand! I write the letter in English using her name and she signs it.

When you are applying for the Non O evisa they will have several options. Click other and then click over 50 pensioner. They won't ask for an invitation letter there. They do ask for proof of 800k (or equivalent) in your home country bank though. That's how i did mine and it went through, good luck.

My understanding is you’ll have to register as a landlord yourself. I haven’t done this yet but will be in the same boat in the near future. I’m told the first time you’ll have to do it in person and that you can then register online to do TM 30s for whoever stays at your residence.

What Embassy and did they actually make a request for documents or are you filling out the initial application form?

Roger Jones you don't need an invitation letter from anyone for the application to the 90-days Non-Imm-O Visa. You need to check the many "or" between the requirements that are listed . . . . . You got the viable option to book a few nights in a hotel and upload the booking confirmation, instead of an "invitation letter"
