Neither a paid extension of stay nor a free border bounce will cause the visa to be revoked or invalidated. That is just mot true. It is a 5 year visa. And for those 5 years you can enter as many times as you want - with or without optional extensions in between.
No idea what the thinking behind opening the DTV for attending classes was - the ED visa were already in place for that (albeit bureaucratic). But, if it works, be happy, free, and enjoy.
Doubt it. From what I remember, some consulates said 6 months + activities count. Then again, the government announcements and example before explicitly mentioned cooking classes. While the workcation / remote working side of things is pretty clear, the "Thai Soft Power" category remains a mystery. Time will tell.
I am not sure a tax return is necessary. As for uploads, you can upload PDFs which can have several pages. You can make a single PDF out of several scans. A (free) tool like the following can help:
That sounds exactly what I hoped it to be. I will check Hat Yai out soon. Gotta be prepared for when Chiang Mai has had its tipping point suffering from too much mass tourism. Sounds like Hat Yai might at least be a good hideaway for burning season in the north. Thank you for sharing.
Do you live in Hat Yai? If so, how is life there? I always wanted to try living there for a while. Kind of seems it could be the Chiang Mai of the south. I have been living in Nakhon Si Thammarat for a while … but that is very, very local.
