Thanks for the comment regarding my question asking about International Driving Permits. I went to the Licensing Centre near Big C, Chiang Mai and was told I would need a 'Certificate of Residence' for the Permit and one for my license to be corrected, I have a new passport so the number is incorrect on license. My next problem is which Immigration form do I use, for Certificate of Residence? I have found 3 up to now TM 18, TM 20 and one with no number. Any help would be useful I can of course just go and ask but if I can download the correct one so much the better.

Thanks in advance
