The only way you can do that is using a Visa agent

Cannot transfer a TV to a long term Visa within Thailand

Cheaper & easier to apply for the Non-O single entry in your home country

Do you have the money for the 800 K ?

In regards to insurance Coming over I recommend getting 30 days cover from your home country

Then when you arrive work on getting Thai insurance cover

- You will require an IDP to ride a motorcycle .

Depending on your home country , IDP is only valid here for 90 days and you are then required to get a Thai license ( but you need an IDP from home )

Water 100 baht - 150 baht
