A thai language course is not a valid soft power for the DTV so may be that was the issue? Perhaps she was on a different visa thats why they deleted the post. You can have a muay thai course over a 6 month period but you can complete the course over a longer time frame doing the same lessons with a few at each visit to thailand. so for example you can spread it over a year or 2 attending classes over a longer time frame so you dont need to complete it within 6 months they are very flexible.
Since you are only looking to be in thailand for 6 months at a time why dont you look at the dtv soft power that way you have any money tied up in thailand only in your own account in your own country and of course good for 5 years?
simple he asked can you and the answer is yes. I also said its not the best rate but it is safe as its bank to bank. I never gave advice I answered his question
thats ok you should get stamped in up to your extension expiry date i.e more than 90 days. The initial non O will give you a 90 day stamp, you now have an extension so you can stay in thailand up to your extension date and then renew
is just read your other posts and see you are on an extension on a type O retirement visa and have multiple entry. If this is true then just go through immigration as normal show your visa and you will get stamped in for the duration of your visa extension.
