Presently on an O-A visa and thinking of doing the 1 year extension here in Thailand before returning to Australia in March. I’m hoping I can return using it as it seems they are letting O-A visa holders back in to Thailand meeting the requirements. Is that correct?
TLDR : Answer Summary
You can return to Thailand on an O-A visa after successfully obtaining a one-year extension, provided you meet all requirements, including quarantine and health insurance. Additionally, ensure you fulfill the financial prerequisites for the extension, which include having 800,000 baht in a Thai bank account or a consistent monthly transfer to meet the total. Note that you also require approval from the Australian government for your travel.
