tried to get a re-entry on no visa? Ahhh no, do you think it makes sense that you can get a re-entry permit for no visa? What exactly would the entry permit be attached to if they don't have any visa? 🤷♂️ But if you want to try it, let us all know how you get on 👍🏻
I got a residence cert on a tourist visa. Depends where your staying, Bangkok seems to be the odd one out where you need to have done a 90 day report before you can get a residence cert.
If you're in the UK why not gor for either a 60 tourist visa or a 6 month multi entry? An actual visa would probably raise less questions than move visa exempt entries.
