You are probably not going to be able to enter visa exempt as you just finished an education visa and the extension out of it, and anyone with an ED visa in their passport is getting extra scrutiny at the border.
Immigration at the border will likely ask you why you are back already after just spending a year in Thailand and tell you that you are trying to live in Thailand on a short term stay, and potentially deny you entry.
And they will address you in Thai, they will speak Thai to you and expect you to understand, after having attended (actually attended and not missed one hour!) a Thai language school.
If you go outside of Thailand and apply for a tourist visa at a Thai consulate, you will get stamped in for 60 days, too, but it's not likely to make much of a difference as they may say the same thing they will say if you try to enter visa-exempt, which is that you just spent a year in Thailand and you are not a tourist, so you cannot do a touristic entry
not an option anymore except if you already have a Thai bank account. If not, you must have missed the news of the recent months. You can't get a Thai bank account opened anymore on a touristic entry. A Thai bank account with 800,000 THB sitting in it however is the pre-requisite to do the "change of visa type" to a Non-Imm-O visa inside Thailand
entering on a Non-Imm-O Retirement Visa, you get stamped in for a 90-days stay permit. This stay permit you get extended on Immigration for a full year. And then every year, year for year, you apply for the next 1-year Extension, again- Actually the extension process is the same one that you need to do if you started out on a Non-Imm-O/A Visa, but after having started on a Non-Imm-O Visa, you keep your freedom of choice regarding your health insurance, because it is not mandatory. If you start on the O/A visa, a Thai private health insurance is mandatory for every yearly extension
you keep your freedom of choice regarding the health insurance, when you start on a 90-days Non-O Retirement Visa. If you start out on a Non-O/A Longstay Visa, you will be forced to buy an almost worthlesss Thai private health insurance once you enter the third year after the first year on a Non-O/A visa. And these Thai insurances won't take you in anew after you passed the age of 70 (only some - and expensive ones! - do that until age 75)
"I just mean the initial application for the non O here in the UK" , , is that you can upload account statements which prove that you have a minimum of like 22,000 GBP (an equivalent of 800,000 THB by current exchange rate) sitting in your UK bank account on the day you apply for the E-visa
. . . . ."But if you mean in ANY bank, no you cannot unless you can provide financial evidence showing monthly income of no less than 65,000 THB (£1,500)." . . . . . . . . I hate to call a group moderator wrong. He can use funds of an equivalent of 800,000 THB in GBP in his UK bank account, OR original UK income statements for the application to the visa itself, through the online E-Visa application processed by the London Thai embassy. In Thailand, However he cannot use income statements anymore as a proof of finances. On Immigration in Thailand, he will need a minimum of 800,000 THB in his Thai bank account to fulfill the requirements for a 1-year Extension of the Stay Permit
well it is like Brandon said: the Non-Imm-O retirement visa is not listed on the WEBSITE of the Royal Thai Embassy Singapore, however it will show being applicable once you start the E-Visa Online application
for this 60-days "family visit" extension you need to show Immigration a freshly printed "Kor Ror 22" from the Amphur office. A "marriage registry printout" that shows your marriage has been registered inside Thailand and is still ongoing
