ORIGINAL POSTER@Mark *****
this is confusing about Thailand in the category when you read it are as follows Non O - 90 days retirement visa which activated by going in and out of Thailand every 90 days
Non OA - 1 year long stay visa required 800k in the bank ( which what part of we submitted at the immigration in Thailand)
Non OX - 10 years visa divided into 5 years needs more money in the bank.
Anyway we are aware that you cannot change category whilst inside Thailand but I thought only applies for Non Ed or B or O however we didn't realized it does also apply for Non O to Non OA. Anyways thanks for the info, we will get in touch with the embassy to apply for new OA visa category. We have all the required documents ready.
