Hi,
I'm arriving in Thailand on a tourist visa and am unable to file the TM 30 on Thailand's immigration website. As I will be staying at a hotel for a week and after staying at my own accommodation, will the hotel be able to file the TM30 on my behalf and should I be filing the application for extension right after my stay in the hotel? Will immigration ask or do I have to declare in the form that I'm no longer staying at the hotel but at my own residence?
Can the filing for visa extension be done anytime during my stay or must it be towards the tail end of my visa period?
TLDR : Answer Summary
The hotel you stay at is obligated to file the TM30 on your behalf upon your check-in. It's advisable to ask for a screenshot of the filing for proof, should you need it for Thai immigration. As for the visa extension, you can file for it anytime during your stay, but it’s typically recommended to do so before your initial 30-day period ends.
