I shared my experience based on real project. We went on startup track even before knowing that there is this type of Visa. So just FYI in case anyone here has an idea to build a tech related business. This will be a good option for you. but I am Thai by the way. So I am not seeking any Visa extension here. 😅 just FYI. Good luck to you all ka 🥰
Suggest applying for smart visa (S type for 6 months). But surely you gotta come up with some business idea and try to make it happen. this can be converted within Thailand. The process is 1.5 month (30 business days) waiting for approval after all docs submitted and make sure that your current one is still valid until the result comes.
