Okay.. a couple of things to chew over here.. do you have to upload a booking confirmation or just input a flight number.. if the latter you could use an 'intended' flight.. meaning one you haven't booked yet but is highly probable if everything comes together.. if you need a booking slip then there are organisations that specialise in solving your problem.. eg. the likes of on ward travel spring to mind.. but there are others.. another alternative is to buy a ticket with an airline that allows you the flexibility to change your travel date without incurring a huge admin fee or other charges.. as regards dates you need to remember that once you are granted a 60-day multi-entry tourist visa in the Uk.. it must be activated within 3 months of the issue date.. so if you are still in the Uk after 90-days you can't use that visa and would need to re-apply.. so you should only apply for it once you know you will be able to travel within that 90-day window.. bear in mind there will usually be a significant delay from the time you find a committed buyer to the completion date of the transaction.. which will vary depending upon the depth of the chain.. if the chain is 3, 4, or 5 parties deep it could take up to 3 months to finalise.. whereas if you sell to a first time buyer that could be reduced to 5-6 weeks.. and since your visa application could be turned around in a couple of weeks say.. you would be wise to wait until you have a buyer and can evaluate the situation better.. so if leaving the Uk is wholly dependent on your house sale being completed.. there's little point in putting your visa application in to the Thai embassy until you have exchanged contracts on the sale.. just my tuppence worth my friend 😉
Sorry to pull you up my friend.. but the deposits to your Thai bank account to justify a switch to the income method do not need to come from earned income in Thailand.. they can come from an overseas source and that source does not need to be disclosed.. they just need to see deposits above the threshold level each and every month.. with no breaks in the chain of deposits.. meaning 12 deposits of at least 40,000 baht for the married visa.. ie. you can't evidence 11 deposits that add up to the same 480,000 baht over the year.. because you remitted 80,000 one month and missed a month along the way.. any break in your regular monthly deposits will disqualify this method for that year and you'd have to use the 400k savings method instead 😉
Actually, i have to concur it's 2-months prior (and 2-months post) for a non-o married visa regardless of whether it's your first or a subsequent application.
If you check it out.. you'll see it's a 6-month visa with a maximum stay of 60-days on each entry.. so if you exit Thailand after the first 60-days you have the right to re-enter and get another 60-days.. and it doesn't look like it stipulates a minimum period you need to leave between visits.. eg. you don't have to stay out for say 3 or 5 days before coming back in again on that visa.. but please check this out yourself to be sure.. there have been increasing instances of people having a hard time at the border.. when they try to bounce out and back in again once their 60-day visa exempt stamp has expired.. people are being questioned about their intent and being told they won't be allowed back in again without the proper visa.. because immigration can see that in many cases people are trying to live in Thailand without applying for the correct long term visa.. and there's no way of knowing if this policy will get stricter as the months unfold.. but having the multi-entry tourist visa from outset removes this risk for you.. in the event that 60-days plus a 30-day extension is not sufficient time to get your preliminaries sorted for your non-o visa application.. bear in mind if you enter as a tourist with an exempt stamp and then go to a neighbouring country to apply for a preliminary non-o visa.. you will have to spend a period of time in said country to finalise that visa.. with all the added expenses that that trip would entail.. so unless I've overlooked something obvious this appears to be the best solution.. I'd invite others in the community to pick holes in this strategy.. should they think this won't work for some reason.. happy to be corrected if my interpretation is flawed 👍
Okay.. so how about applying for a 60-day multiple entry tourist visa instead.. which you can extend by 30-days in country to give you an initial 90-days.. which you can use again to re-enter if you need to bounce out and back in again during the 6-month validity period.. though you should be able to knock things into shape within the first 90-days this gives you a back up plan.. because you can't be denied entry upon your return from a neighbouring country.. like some folk doing 'border runs' are now finding.. just a thought for consideration 👍
You will be switching both the reason for the visa.. from retirement to marriage.. as well as the financial obligation.. from savings to income.. at the same time.. if you were simply extending on the same basis.. ie. for retirement.. then you shouldn't have a problem.. but there is a possibility that immigration consider the switch of basis to marriage as a first application under that category.. and then deny you use of the income method.. because it can only be used from the first extension onwards.. so you need to check this out.. if you did not have your own funds in place when you submitted your last application.. and used an agent to solve that problem.. then you should also be aware that immigration may want to check that the funds remained in the account for the requisite period after the visa was issued.. which could lead them to re-checking that the seasoning of funds was also met last time around.. if you now have the 400k sum in the bank it may be better to abandon the idea of 'switching' altogether.. if you just leave and re-enter the country near the visa expiry date.. without a re-entry permit.. you will re-set the clock.. and can apply for the married visa without connecting it to your previous retirement visa.. thereby alleviating the scrutiny that a conversion might draw.. but again , your original plan might work.. provided the IO you get on the day is not as diligent as one of his colleagues may be!
Why not apply for a non-o visa while you are still in the Uk.. and enter Thailand using that.. which gives you 90-days to get your ducks in a row so to speak.
