No.. In any event the OP was not asking about applying for a non O based on retirement.

Did you read the OP? He was was asking about a ME Non O based on retirement. Your post re based in marriage is completely irrelevant.

OP, @Caldera and @BritTim Have given best advice. what is your plan after exit Thailand? Assume if you plan to reenter Thailand that you have not used your 2 visa exempt visa land border per calendar year.

Report not long ago of multi entry non O 12 month e-visa from UK. (London)

The flight won't be the issue. You need to check if the border crossing you use will process overstay. Nong Khai? How many day overstay

"Anyway you can keep....." :NO You will need start over..

Samut Prakan is a nonsense office.

A point form of documents you provided would be more helpful.. You did not mention one. You did state... "The air conditioning, lack of a queue (and lack of critical perusal of any details) helped the ambience no end." Really?

Stop nonsense posts. Not helpful

Where on earth does that come from. CW imo one of the most consistent immigration offices. CW for example follows change of rules to TM30. CM (one example) does not. I personally have dealt with CW for 10 years and NEVER even filed a TM30. True same address for those 10 yr. I find the OP confusing in this thread. Do you even deal with CW? Please point to "ROGUE OFFICE" examples.

Thinking you are doing the confusing. I use 2 accounts same bank both as dedicated accounts for extensions retirement. One is a fixed account which is 600k+ which covers the months where you can drop to the 400k minimum amount if required. The other is a savings account which normally has 400k. Kasikorn provide one bank letter listing both accounts. Dealing with CW it's easy to do that on day of application. Everyone has their own formula

Some do ..... Think UK do. Few and far between..

Immigration offices vary. Couple of weeks is the norm for extensions from visa exempt and SETV

They may be very nice however regards your TM30... Presumably you would have had a reentry permit for your trip out of Thailand so a TM30 should not be required. Also offices that try to "help" with doing a 90 day report are not really helping. Those using online reporting best to keep 90 reports separate from extension.

Forget income method. You need to maintain 800k + for 3 months after application and for 2 months prior to next application. Not below 400k at other times. Very simple. If funds not an issue some folk (I'm one) just park 800k+ in a dedicated bank account all year round. Avoids accidents

No problem

You have a non O based on marriage? You can apply for 60 day extension to visit wife. Usually that would be done in last couple of weeks of expiry of your stamp

The OP was giving report. I would think everyone living in Thailand on extensions from non O would be very aware of option of using an agent for extensions based on retirement. The 12,500b you parrot is from agents in Pattaya. Your post is off topic and boring. OP did not ask about agents.

Are you living ongoing in Thailand. Why did you need to do a TM30? Was your 90 day report due and you took opportunity to file TM47 while you were there?

Which immigration office. You cannot obtain certificate of residence at CW without 90 day report.

I understand your concerns. This won't help much but prior to covid I was flying out/in Thailand maybe 2 times a month. I would sometimes observe folk next counter being questioned. A clear itinerary with planned stay seemed to be best option. A flight out (you can rent a flight 12usd) also good addition. Funds 20k is a given but they can ignore. Good luck

Might be messy but you could provide a TM30 or rental agreement (even if a dud) at normal office such as CW to obtain a non O. The issue is that you would need to obtain 12 month extension at that office. Perhaps attend Roi Et office and obtain first hand info. Fall back would be use other office. Would require a TM30 at the very least

The 8.5 month validity is not huge issue. It just means that you extension from non O retirement will have expiry dated till expiry of pp. No big deal. You lose few months. You should ditch non O-A and enter Thailand visa exempt and obtain a non O at your immigration office and subsequent extension.

More important when date next entry to Thailand with SETV or visa exempt if TV Not approved.

Bit off topic but cop this... Few months back I asked Thai partner to go renew her expired pp. So next day trotted off to local place that can accept application. Now the punch line. The new pp was EMS mailed to our condo two days later. I would beg for 3/4 weeks in Oz.
