It is my guess that this is an error on the e-visa website following recent updates. Others have reported the problem. If you can afford to wait a week or two before making the application, I advise you to do so. Such a basic error should be corrected reasonably quickly one would think. If you cannot afford to wait, contact the embassy for advice.

On the assumption that the man's income (transferred to a Thai bank account) is all the money that the family have to live on, and foreign credit/debit cards are not used, maybe so. It is unclear, even in that case though, that the wife and children would be better off if their provider was not present. As is often pointed out, a foreign woman can stay with her Thai husband without showing any income at all.

If you are living with a teenaged child in Thailand, it should be possible to get this sorted out with just a supporting letter from your wife. You might run into roadblocks at the amphoe or immigration office, but it should be possible to get things sorted out. You will need the child with you at both the amphoe and at immigration.

If you look at their schedule of fees (https://image.mfa.go.th/mfa/0/nrpgTpGLMX/Consular_Fee_9_May_2022.pdf) the multiple entry Non O visa is there. That does not mean they actually issue it. The only way to know is to ask.

Good luck! I will be very surprised if airport immigration will stamp you in just based on a photocopy of the re-entry permit. Indeed, you might even have a problem at airline check in. This seems like a major problem which has been created through no fault of your own. You have my sympathy.

I am not sure if you are saying it is unfair that Immigration push the responsibility onto you (I agree) or are denying that they do.

To be fair, it is not exactly the same each year. Many offices will find it necessary to tell you to provide something never needed before. Further, using the same photographs as before is not permitted. They need evidence that your house number, bedroom etc. still exist.

Nice in theory. The reality is different (though it does depend a bit on the immigration office). Most often, if you are renting, the officials do not want to go to the trouble of chasing your landlord. Instead, they will state that you are the "possessor", and it is your responsibility to ensure that the TM30 notification is done.

Yes

It has been tried, sometimes successfully, sometimes not. Besides using a VPN, it will be necessary to falsify the required copies of pages from your passport. If lots of people start trying this, they will probably start employing VPN detectors, and block access to the e-visa site through a VPN. That would be unfortunate as there can be legitimate reasons for using a VPN.

That is actually an ancient requirement that was only in force for a few months and was rescinded (as I recall) about 10 years ago or so. As usual, embassy/consulate websites cannot be relied upon to provide accurate information on anything other than the services they provide themselves (and sometimes not even then).

There should be no fee for submitting a TM30 notification, whether done online or in person.

Tak immigration does not have a good reputation, but there should be no problem with a 30-day extension anywhere. The border crossing at Maesot is currently closed, with no prospect of an early reopening. Enjoy your holiday. If you plan cycling around Tak province, I hope you are fit.

You have everything important covered. Just a couple of notes on less important matters. Officially, returning from abroad on a re-entry permit, you do not have to do a new TM30 notification. However, some immigration offices demand that one is done. Your next 90-day address report, after your return, will be due in June (90 days after your return).

This is unclear. I would not be surprised if HCMC require the money to have been in the account for a couple of months, while Savannakhet just want to see evidence that it is/was there shortly before the application.

There have been multiple credible reports. I believe it.

Be sure you understand the big difference between two approaches: At the time your extension of stay based on working is cancelled, you apply for a new extension (either 60-day to visit your Thai spouse, or a one-year extension based on marriage to a Thai). When you employment ends, you leave Thailand, and return either with a Non O visa based on Thai spouse or a visa exemption. In the latter case, you will apply for a Non O visa at Immigration. You cannot apply for a new visa at Immigration when already in Thailand on a Non Immigrant entry. A 60-day extension is easy. The main condition is that you have not had one since the last time you entered Thailand with a new visa. Entering with a re-entry permit does not entitle you to an extra 60-day extension. To apply for a one-year extension based on marriage, you must have 400k baht in a Thai bank account for at least two months on the day you apply. This minimum seasoning duration is fixed, although the senior official does have discretion to waive it. The financial seasoning is virtually never relaxed unless you go through an agent. An application for a Non O visa at Immigration requires 400k baht in your account on the day you apply.

The reason it works is because it is 100% indistinguishable from a fully paid up ticket.

If no Thai employer or customers, it is 100% tolerated. It is not strictly legal.

Nearby countries where you can apply for a multiple entry Non O are restricted to HCMC and Savannakhet. Your home country might be a good place to apply, but I assume that is not an attractive option for you. There are rumours that Colombo can flexible when it comes to visa applications. If absolutely desperate, you could try there. No guarantees.

Make sure the Thai bank account remains open. Ensuring there is 1,000 baht or so in the account should ensure this. When ready to return, get a single entry Non O visa before leaving home country. Make sure the 400k baht is transferred into the Thai account. The rest should be easy.

They will expect the departure date to be within 60 days of arrival, and want your exit flight reservation to reflect that. However, the dates you specify are not binding, and can be changed later.

To apply for a visa at an embassy/consulate, you must be outside of the country at the time of the application. To apply for a SMRT visa, Thailand Elite, LTR visa, Non O-X visa, Non Immigrant visa at Immigration etc., there is no regulation that you must apply from outside Thailand. Of course, you can claim that none of these are "visas", but I believe such a claim would be incorrect.

Politically correct these days, if you do not know the person's preferred pronouns, is to use "they". It is a reflection of my age that I still wince every time I need to do this, although I do comply.

When dealing with airlines, the best source to convince the ignorant is the IATA guidelines which member airlines are strongly recommended to follow. It should be noted that IATA tries to keep track of member airlines that depart from their recommendations, and their Travel Center (https://www.iatatravelcentre.com/) takes account of the known deviations. Even stubborn check-in staff will normally accept what IATA says about their airline's policies.
