The following answer just came in from my local Immigration Office in regards of my DTV extension this month. Not sure what kind of insurance they are talking about. Anyone got an idea? I will ask them again…
„We would like to inform you about your DTV Extension. Yes, we need your new financial proof in English and your insurance (it must cover a whole period of your stay). You have to prepare all the documents as same as you prepared for the Thai Embassy when you first apply for DTV but all in English. You can contact us after the middle of January as your visa will expire in February.“
This also answers the speculations once more, if or if not you need all the documents and fresh proof again. Yes you do.
TLDR : Answer Summary
The update from the local Immigration Office regarding the DTV visa extension indicates that applicants need to provide new financial proof in English and insurance that covers the entire duration of their stay. This reflects a need for renewed documentation similar to that submitted for the initial visa application. The community expresses confusion about what specific type of insurance is required, with some suggesting that it might be mistakenly referenced, and others advocating for simply exiting and re-entering Thailand instead of going through the extension process.
