That just doesn't make any sense at all, though.
Visa validity 5 years, multi entry.
If each entry permitted a stay of 180 days, then with border runs you could stay for the full 5 years, so what would be the point of a one time 180 day extension?
And on offer for just 10K, it would undermine the LTR and O-X visa types.
We have to bear in mind the purpose of this new visa type.
Mr. Chai Watcharong, spokesman for the Prime Minister's Office, stated;
"Add a new type of visa, Destination Thailand Visa (DTV), for foreigners who have skills and work remotely through the digital system (remote worker or digital nomad) who wish to Will be staying in Thailand to work and travel at the same time, with employers and customers abroad It is also a destination for foreigners who want to do cultural activities and use medical services. However, Thailand does not yet have a visa that supports this group of foreigners. This is a group of people who have the potential and will be beneficial to the development of the country."
The key wording 'to work and travel at the same time, with employers and customers abroad'.
That suggests the visa will allow unlimited entries, but with a limit of staying in Thailand for only 180 days per year.
The one time 180 day extension then makes much more sense.
Of course, we could be both total incorrect, when the full details are revealed.
