Well you cannot work for the Thai company that the Smart S is based on with the DTV. I woukd imagine, ie am guessing, you would need to cancel the S and close the Thai legal entity. I was recently considering the Smart S myself but with the DTV we are re-evaluating. We are waiting to see how it works out first though
I could not go from Retirement Visa O direct to Business Visa B for a WP. I had to have my O cancelled. I could then leave the country and apply for the B at the Singapore Embassy. I do not know how it will work with DTV but nobody is getting a WP on a DTV
Good points. The problem may arise in the future as they did with Ed Visa. Immigration might want to see proof of actual improvement and learning or even ongoing enrollment.
Peope have got the DTV with a 2 week cookery course. Might they tighten up in the future? Nobody knows. Might immigration ask for ongoing learning etc in future before allowing re-entry or even entry? Nobody knows.
If he gets a Work Permit he would already need to have a different visa ie a B. I think he wants to look for a job and then get a WP on the DTV which is not possible. The process is get a job. The employer applies for a WP at ministry of labour. You take the letter issued along with employer and employee documents to apply for a visa ie B. That is issued and is taken to Ministry of Labour. They issue the WP and yiu take that to Immigration and the visa ie B is extended to same length as the WP.
You can do remote work with companies and individuals outside of Thailand with a DTV. Once you work within Thailand for a local legal entity you need a Work Permit. For example of you are on a DTV based in Chaing Mai and want to work for a Thai legal entity based in Phuket you cannot legally do so on a DTV. However, what I'd the Thai legal entity engaged a Ltd company based in the UK for example and you consulted for that UK company. Strictly now allowed but how would anyone know?
Singapore was always a strange Embassy. When I worked in Singapore there was always one particular member of staff mentioned on the message boards. She has to be gone now. I last dealt with them for a B Visa and they were efficient and pleasant.
