Can others confirm their experience with this please? Staying with a friend who probably cannot fill this based on the apartment she renting, so I will try the hotel/hostel route. It seems the TM-30 form has a checkout date to fill in too however, so will this still work if the checkout date has already passed by the time you turn up at immigration for a 30 day extension?
And if anyone can recommend a reliable agency around Sukhimvit Asoke/Phrom Phong to make the trip to immigration on my behalf, that would be a welcome too.
