As soon as you get a visa you need to check the details.
a Thai Wife absolutely does not need a Work Permit to work inside Thailand, so both people do not have the Thai Nationality, How could you accept on receiving this Visa the text based on Thai wife?
I understand mistakes are made by an Embassy, but accepting being a Thai and then travel with that visa is taking a risk as denied entry is a big possibility by using this incorrect visa.
There is officially no maximum on how many times a year you can use the Visa Exempt Entry by air, but every time you have to hand over your passport to an Immigration Officer who has a duty to check why people come to Thailand.
There is a small difference, it will be the same period of 30 days Visa Exempt Entry and you can also extend this once with another 30 days but you can only enter twice a calendar year by land borders using this 30 day Visa Exempt Entry Scheme
Correct, it will be case by case as different people have different incomes and it will be impossible to write out all the options.
But Document in foreign languages must be translated into Thai. If translated into English, it should be notarized by notary organs or the applicant’s diplomatic/ consular mission.
