At my last tourist visa extension at Laksi, I recall having to fill up one other form besides the TM7.  Would anyone know what that is, and where I can download it?  TIA.
Also just to confirm, I only need to photocopy  the data page of my passport and the page with  the latest stamp coming in ? No other pages? 
So documents to hand in are just:  passport, one PHOTO, TM 7, TM 30,  copies of Passport data page, latest stamp, plus 1900 baht.
