Can I run a business while on a retirement visa?

"I just want to share with others whom are considering using them, that BaanSmile is an excellent service. They helped me with my STV visa. They helped me every step of the way. This was during a time where it was quite complex getting any visa in Thailand. During the application process, they were excellent especially regarding answering emails quickly and clearly. If there were any issues regarding the requirements I provided, they would inform me and help correct the issue. They had what seemed to be a perfectionist approach. It was very comforting. Everything went really well and it was hassle free. I also had them help me with my subsequent 90 day extension/report. That also went very well and hassle free. There’s no way I could have managed doing all of these processes on my own this smoothly. I’m very grateful and I continue to use there service till this day for my visa purposes in Thailand. I highly recommend them."
