Am I eligible to apply for a Non-O visa in Thailand having a Non-OA visa?

And as a Canadian your Embassy in Bangkok can provide you with an Affidavit of Income to use with Thai immigration to obtain the Non O Visa as retiree and the One year extension of stay as retired. With NO PROOF OF 800,000 Thai baht in a Thai bank account in your name only.

IF you can show your Canadian Embassy your annual income and savings are at least or greater than 800,000 Thai baht...

This may be an option for you to consider.

Basically, you are eligible for a Non-O retirement visa.

But you cannot apply for a visa when you have a still valid visa in your passport (or eVisa as PDF) already.

You would be stamped based on Non-OA when you enter Thailand on 12th November, for 1 more year or the same as your insurance coverage. If your insurance is not enough, you will be stamped for 45 days as a visa-exempt.

Possible options for you might be:

1. Enter on Non-OA on 12th Nov, do border-bounce at the end of your new 1 year and re-enter on visa-exempt, then do an in-country visa application.

2. Ask IO not to use Non-OA, but on visa-exempt entry at the passport control upon arrival in Thailand on 12th Nov. If you are approved entry on visa-exempt, then do an in-country visa application.

3. Wait until after 22nd Nov then enter Thailand to do the in-country process.

Once you enter on visa-exempt, you seem to be good to apply for in-country Non-O.

Here is the general information for in-country Non-O based on being over 50. You need to get the latest version from your immigration office.
