Be careful how you approach the DTV for what you are thinking. Each time you enter you run the risk of being asked to prove the medical treatments and appointments and the cooking course. They are checking and will be checking more in the future. If you use a cooking course for say 6 months then what are you doing there next year? No course no 6 month stamp. It will happen.
I’ve seen people fined for not. It’s best to do straight away.
Also consider that DLT might only accept in the 1st 90 days for conversion. And each police and DLT will have to ere own interpretations of the law, same as immigration so things differently in different places.
It’s Thailand that is normal, what works where I am in Samui won’t always work elsewhere.
be careful with that, many people. Get fined believing that, but the police might not know that, and will fine you anyway, you can’t argue because that is disrespectful and will end up with more issues and bigger fines. 🤪
It’s a catch 22 situation for applications such as this, because you would technically be in breach of your current visa. You can’t work remotely on an ED visa, so starting and running a business while here and not doing anything else won’t be an issue, but moving forward it possibly might and while only a very small chance, the way Thailand works you just never know what they will do.
