@Tod ********
I just spoke with my landlord and they said to come and see them and they'll arrange the tm30 today.
Do you think it'll get through in time? I'm planning to go on Tuesday, and have booked an appointment at Vientiane for the following Monday in case it goes wrong.
Would it be perhaps easier just to go to chonburi and do it the extension there? My current tm30 is registered to an address there, and it's not much further from my bangkok place (and way less hassle the Chang wattana)
