Hey folks, I have a question regarding a 45-day visa exemption transfer to new passport:

I entered Thailand with a 45-day visa exemption, and I am getting a new passport here in BKK as my old one is full.

* What other document are required for a stamp transfer?

* Do I need to get a confirmation letter from my embassy (as they suggested)? Or can I just go immigration with my 2 passports?

* I am planning to go to immigration for both the transfer and the 30-day extension at the same time. Or should I do it separately?

* And lastly, will I have more chance and less hassle if I do it in Phuket than in Bangkok?

Thanks in advance
