I have a Honda Phantom that I bought in Nong Khai a few years ago. I live in Korat province and at the time for various reasons it was more advantageous to leave the greenbook as registered in Nong Khai province. The bike is registered in my name and has my Nakhorn Ratchasima address. I have had no problem each year paying the "land" tax here at the land office in Korat. My question, is there any particular advantage for me to go ahead and get the greenbook and license plate changed from Nong Khai province to Nakhon Ratchasima province?
