What are the steps for renewing a retirement visa in Thailand?

@Franco ******

You are confusing us with wrong wording :

There is nothing such as a “renowal visa retirement”

The only thing you can “renew”, is the “1-year Extended Stay Permit based on Retirement”, by applying for the next “1-year Extension of the Stay Permit based on Retirement”

There is a difference between a "visa" and a "stay permit"

The visa permits and regulates the entry into the country. Depending on the visa category, you will receive stay permits of varying lengths.

In Thailand, these can be 15, 30, 60, 90, or 180 days – depending on the visa category. It can also be 1 years or 5 years

The stay permit regulates the length of your permitted stay in the country. The length of the permitted stay depends on the visa category.

You enter the country on a visa - and from then on reside in the country on a stay permit. This be seen on the entry stamp:

It says "admitted until" and a date. This stamp is the actual stay permit. The entry date is in red, and the expiration date of the "admitted until" permit is in blue.

In the upper right corner there will be a smallish note indicating the visa class you used

The stamp for the annual "1-year extension of residence permit" consequently reads "extension of stay permitted until" and a date.

The reason for which the 12-months extension got issued, is either an extra stamp saying “Retirement” or a handwritten note saying “Thai Wife”

This stamp is the actual stay permit. This stamp is not a visa.

A visa, for example, a "single entry tourist" or a "single entry Non-Imm-O" visa type, becomes invalid upon entry and cannot be extended or used again for another entry.

A multi-entry visa can be used for any number of (multiple) entries within the visa validity period.

For example, the 6-month multi-entry tourist visa is valid for 6 months, but you only receive a 60-days stay permit for each entry.

A visa always has a so-called "visa validity." This is the expiration date by which you must have used the visa to enter the country.

Visas .pdf documents issued by the e-visa online system, show the expiry date of the visa validity after the words "visa must be used by".

EXAMPLE: For a 60-day tourist visa or a 90-day non-immigrant visa, the visa validity is three months from the date of issue.

A 3-months visa validity date means you must have entered the country by this date, 3 months after the visa has been issued.

The visa validity and the validity of the permitted stay are never the same.

Anyone who wants to extend their stay must apply for an "extended stay permit" and not a "visa extension."

Even Thai Immigration fools around "visa extensions," even though they aren't extending any visas. They are only extending the stay permit.

Laziness plays a role. It's easier to say you have a "retirement visa" than to pronounce the correct term, which is "temporary extension of the stay permit based on retirement."

Look at your entry stamp and check the visa validity date. Compare. Your stamped stay permit extends BEYOND the visa expiration date. The entry date is in red, and the expiration date of the "admitted until" permit is in blue.

NOTE:

The entry is made on a "visa."

A "stay permit" is stamped in the passport.

The VISA expires and is invalid after entry.

The applicant is now in Thailand on a stay permit.

This stay permit can be extended. A visa that has long since expired, cannot get extended at all.
