I guess this answers the questions:

Just to explain: TM30 stands for registration of a foreigner residing on an address in Thailand, so without having an address it is impossibile to report that you are more than 90 days inside Thailand and still living at the same address, this by using the TM47 form.

As you work inside Thailand you only have to show your tax and sso payments of the last 3 months from you and the Thai staff needed to get the work permit.

You can apply during every 90 day of stay you got on entry with this visa and do not have to wait until the visa itself expires

Be aware that the visa is valid from the moment it is issued, please check what kind of visa you are going to apply for.

Retirement Visa is a short cut name used for the

1, Non Immigrant O visa, single entry

2, Non Immigrant O visa, no entry

3. Non Immigrant O visa Multiple Entry

4. Non Immigrant O-A visa

5. Non Immigrant O-X visa

6. Long Term Visa, short LTR visa

7. Extension of Stay.

All these have different requirements, rules and regulations, so it is very difficult to give proper advice on request about retirement visa.

So use the same ticket

If you applied for a Single Entry Tourist Visa you had to show onward travel, so why you not use the same ticket when asked?

NO, your status and history is registerd in the Immigration Database and will not be deleted on 31 Dec at midnight.

BUT if you try to abuse and maximize the use of the 30 day Visa Exempt Entry, than yes, the rules is maximum 2 x by land borders in one calendar year.

a Letther from the Thai bank where you have the account.

That is correct, BUT as soon as your wife applied for and been issued the 1 YEAR Extension of Stay based on being over 50 years of age, which means she has long stay in Thailand you are able to apply.

NOT as you asked during the 90 days visits with a Non Immigrant O visa.

Always amazing that on a Sunday, when Immigration Offices are closed, a staff member informs all expats that there are new requirements.
