I returned to Thailand from a holiday in Turkey on June 1st and the online reporting worked fine. It seems to be the case with this system that it works for some and doesn't for others, at least if the comments and feedback on Thai Twitter are anything to go by.
As you say, you can never have too many documents, even if it means keeping half of them in your 'keep back' folder as I call it and pulling them out like rabbits from a hat if required.
I would update my bank book every month if my branch wasn't so inconvenient and difficult to get to. It's just too much hassle to go there 12 times a year. If I had a monthly updated bank book, there would probably be no need to have the printouts at all.
Hi Jim, it's all about getting your ducks in a row regarding the paperwork. If you know EXACTLY what's required, it's very rare to have a curve ball thrown at you. Yes, it's not the most pleasant hour or two and neither is it a day I look forward to, but once again, when I left the building with a new one-year extension and a re-entry permit, I thought 'what were you getting stressed out about?'
I know several people that have had Google maps rejected. I always go with the same hand-drawn map (but it's fairly detailed) and it's always been accepted. Put yourself in immigration's shoes for a moment - could they find your house easily with the map you've drawn? That's probably the criteria.
I was there a few days ago. It has now moved back to its old location by the riverside at Paknam - a five-minute walk from BTS Paknam on the Sukhumwit line.
