Hi everybody, I am a German citizen above 50 and currently here on an METV visa. It is valid until 4 Jan 2020. I have a history of many back to back entries on tourist visas or visa exemptions in the last 2 years. So far never had a problem with that but I read that the IO can reject you anytime even with a valid TV in the passport and I am a bit worried now every time I am coming into Thailand. Now I am planning to go to Germany in December and come back to Thailand before Xmas. I want to take the opportunity to go to the embassy and this time apply for a non-immigrant O-M.

Is this possible still having a valid METV visa in my passport? Can they simply cancel it and put the Non-immigrant O-M inside? Many thanks in advance
