Once you get it translated, make an appointment at the thai passport office on floor 4 at central. For translation, I used a company at the side of Big C, pattaya Klang
I had a tm30 lodged about 2 months ago. Recently was away and stayed in Bangkok, then Koh Tao, then Koh Yao Yai. Total travel period of about 2 weeks. Went to immigration yesterday for a residence certificate and they were happy enough with my original TM30. That was at Jomtien, maybe other areas differ
