(y) go SLOW, get it right, take your time, CHECK the stuff you type in carefully, if you make a mistake on data entry you will get rejected and lose the application fee, ๐
there is no thai embassy website, you get ALL visas to thailand on the eVisa web-portal, if you're in the UK you select that and it'll automatically pick the London Thai embassy for the visa to be processed thru.
You upload all your documents, fill out the application online, submit it, pay for the visa and then wait for it to be approved.
As people said the 6 month METV (mulit-entry tourist visa) will give you unlimited entries of 60 days each for the validity of the visa.
You're coming into the country on a 90 day Non-O visa you got from the consulate in your country before you came here based on retirement <- That IS a retirement visa ๐
Once you're here, you'll bank the funds, wait for it to season the 2 months and until you have 30 days or less left on your 90 day entry stamp. Then you'll go to your immigration office and apply for a yearly "extension of stay" on that Non-O visa. It's 1900 baht and they issue the extension on the spot.
After that you're good to stay for the year the extension is valid.
This is a general list of requirements for an extension based on retirement, it is NOT office specific and you should go to your immigration office and get the hand out listing the requirements for that office and in Hua Hin go to the main office not the Blueport Mall one ๐
at most offices you can come in free stamp 60 day entry, bank the 800K baht and apply for the 90 day Non-O visa in country for 2000baht. it goes under review for usually 2 weeks then you go back to get the Non-O visa and a new 90 day stamp inked in. Then 2 months later you apply for the yearly extension
it's not a hybrid anything, many MANY people do the in country Non-O. Although with the difficulty in opening a bank account free stamp it is often easier to get the Non-O in your country before you come here, so you can open the account and get the funds in
you need to update the bank book the day you apply for the extension (and if that means put money in or take money out to make the machine print the update with the balance and the date you apply that's what you have to do)
AND
You need the bank to print out a 3 month transaction detail report (even though it sounds like you don't have any transactions on that account)
