The problem for us isn't the work permit. Our employer (based in Bangkok) employs a number of home-based staff, working online. When attending Immigration to process their annual Extension, our HR staff were told that it could not be extended without a Bangkok address. Last year this was not an issue, and, although the home-based staff still had to come to Bangkok for the extension, the Extensions were issued for staff with home addresses in Chiang Mai and other provinces. Apparently, that was allowed due to Covid, but now Covid is over all staff must be based in Bangkok.
