Do you have a motorbike licence (not car licence) from your own country? Do you have an IDP? Do you have a Thai licence? They have separate ones for car and bike
You need to prove you're in the UK. They ask for utility bills or you can use your driver licence. I thought my bank statements would be enough but they asked for further proof.
It is called a border bounce. A visa run is when you leave to get a new visa. There is no specified time to be out of the country, but some land border posts can be obstructive in an attempt to obtain some tea money from you. Reports on another group say the Lao crossing at Nong Khai is insisting you stay out a minimum of 2 days, but I don't know if that includes DTV holders or just visa-exempt people.
John Stanners, I've seen this 120k rule quoted before, but it was not mentioned in the tax office. The recent amendment to the existing tax rule, which came into effect on Jan 1st 2024, was regarding untaxed money being brought onshore, and that's all they were interested in.
All other visas are transferred to your new passport — why not a DTV? Immigration transferred my Non-O extension to my new passport at the airport without me even asking.
