I have no patience to go running around trying banks. I phoned tik tok services today, they picked me up, took me to the bank, sorted out all the forms. I left the bank an hour later with bank card, bank app etc. Cost 5000 baht.
Embassy has the right to ask for whatever documents they deem necessary for a particular application. Sure there is a standard list they require but can also require more.
You should choose workcation/remote worker and supply the items/documents that they require for that visa application. There are many people who own their own business who have applied and received the DTV.
