However you can only get the "60-days family visit" extension, if your marriage is acknowledged and registered in Thailand. Because Immigration will want to see a freshly on the Amphur printed "Kor Ror 22" marriage registry as proof of a still existing marriage. If you marriage is only registered abroad, you first need to get it acknowledged inside Thailand

@Vlastimil ******

yes, exactly. Many people do actually base their 5- or 4 months hibernation along with their Thai wives by these means

@Dave ********

you most probably won't be able to do 6 consecutive months out of two visa-exempt entries and their 30 days extension. While it depends on the Immigration officer, it also depends on your stamp history of a recent 365-days period. If you did a touristic entry somewhere along that period, it will be counted against your plan

@Stuart **********

everything is correct, except the part that "before the visa expires". The 90-days Non-Imm-O Visa already expires and becomes used and invalid when you enter Thailand! What you meant is "before the 90-days stay permit expires"

@Simon ********

Myself I would exactly do that, as long as there won't be any repucussions coming from Immigration, should they ask for your calendar year tax receipt when you apply for the next yearly extension. As far as I can see this won't happen, it has already been called off by many Immigration officials who have been interviewed on this matter. They don't want to do the job for the Thai Tax Department

@Paul **********

you can google dual tax agreement and how it works . . . what I meant to say, John Stanners in the next comment put into more accurate words: "The tax you pay in the UK on the income you bring into Thailand can be claimed as a tax credit against Thai tax.". I changed my text accordingly

the U.K. and Thailand have a Dual Taxation Agreement. If you pension has been taxed in the U.K. already, and you can prove it, it won't be taxed again in Thailand (However the tax you pay in the UK on the income you bring into Thailand can be claimed as a tax credit against Thai tax - you need to check this with the local Thai Department of Tax). Rest assured something like 600,000 THB per calendar year will be tax free after all the allowances have been deducted

you can enter on a 90-days Non-Imm-O Family visa, get stamped a 90-days stay permit, and on Immigration can get a 60-days extension based on "family visit" for 1900 Baht. Nobody is forcing you to extend your 90-days stay permit into the 1-year Extension of Stay Permit. However before the 90 plus 60 days = 150 days stay permit expires, you need to exit Thailand. You can't get another 60-days "family visit" extension any more - the limit is ONE per entry

Smithy Tee just a side reminder, because Ally's advice is NOT 100% correct: . . . . a foreign woman married to a Thai husband does NOT need to show any financial proof for the application to the 90-days Non-O family visa, nor for the application to the 12-months Extension on Immigration in Thailand

@Ally ***********

"especially if your wife needs to open a Thai Bank account to season funds in readiness for the extension 👍" . . . . . . sorry I think you have your wires crossed . . . . a foreign woman married to a Thai husband does NOT need to show a financial proof for the 90-days Non-O visa nor for the 12-months Extension
