Good morning all, I'm leaving Thailand tomorrow for a month and its the first time that I'm leaving on my Non o. As its only a single entry I'll need to apply for a re-entry permit. Ive been looking on Google and its says I can get this at Suvarnabhumi after security, I've been through security here countless times and I can honestly say I've never noticed anything between security and immigration. I was hoping someone who has done this at Suvarnahumi could offer a bit more of a detailed explanation as to where to do it. Thanks!
