you can get the 90-days Non-Imm-O marriage Visa in the UK with your UK marriage documents, but in order to apply in Thailand on Immigration for the 1-year extension of the stay permit, you need your marriage registered inside Thailand because Immigration wants to see a Kor Ror 22 marriage registry printout from the Amphur. You need to get your marriage legalized on the Royal Thai Embassy London, and co-legalized in Thailand

@Steve ********

then you don't have any "visa". You have a 12-months extended stay permit. The visa you started with, already became invalid the moment you entered Thailand on it. And it doesn't matter - every Non-Thai needs to fill out the online TDAC before every entry into Thailand

@Maitin ******

if you wish to apply for the 1-year extension, first rule is, the money must have been sitting in your Thai bank account for TWO MONTHS and the bank must issue a letter for the Immigration, in which they confirm this. You cannot just apply for the extension before this "deposit seasoning" period has passed

@Alf **********

you are right . . . i shall change the text

@Alf **********

I had a good laugh at your attempt to clarify my advice . . . . . of course I can say "you need a minimum of 30 days left on your 90-days stay permit before you can apply for the extension" . . to call it "maximum of 30 days" isn't really making any sense, because from the 30 days left you count DOWNWARD, which gives sense to the word "minimum". You could also don't say anything at all, and say "up from 30 days left of the 90-days stay permit you can apply for the extension" . . .trying to sound smart? Give it up, buddy

@NeL ****

no, for the application to a 30-days touristic extension, the fee is 1900 Baht. . . . You CANNOT buy a 30-days extension on top of a 90-days Non-Imm-O Retirement Visa. You can only get the 90-days stay permit you got stamped when you entered Thailand, extended to 1 year, by fulfilling the financial requirements. You can, however, buy a single re-entry permit for 1000 Baht for the 90 days stay permit. A re-entry permit doesn't buy you any extra time - it only keeps the initial 90-days stay permit valid in case you exit and re-enter Thailand within this 90-days period

you could buy a single re-entry permit for 1000 THB, which would keep the 90-days stay permit active when you exit Thailand. However you need to know, at most Immigrations you cannot apply for the 12-months retirement extension unless there is a maximum of 30 days (on some Immigration up from 45 days) left on your 90-days stay permit. For the application to the "retirement extension", you need to visit Immigration personally

@Jair *****

if you stay in the country for full 90 days, you need to report. You do the first report after having entered in person, and can do all future reports online. You have a 21 days window for reporting - 14 days before due date until 7 days after due date

@Jair *****

then the start on a 90-days Non-imm-O and subsequent yearly extensions make more sense than the O/A or O/X visa

@Summer *****

no, a 6-months multi entry Tourist Visa can only be applied for in the country of your residence, so for him this would be the U.S.A.
