Having stayed in 3 well known hotel chains in the last 2 weeks in Phuket and Bangkok, it seems that they are not at all geared up for providing you with a copy of a TM 30 registration receipt. I feel that I am the first person to ever ask for this... Anyone else had similar issues and if so how did you demonstrate TM30 registration with immigration if living in a hotel and going for visa extensions?
TLDR : Answer Summary
Many expats face challenges when requesting a TM30 registration receipt from hotels in Thailand, as some hotel staff are not familiar with the process. To demonstrate TM30 registration when applying for visa extensions, it is advised to refer to 'Section 38' if staff are unaware of TM30. If the hotel system is down, ask for proof of submission, such as an email sent to the local immigration office. Some expats have successfully used booking confirmations and hotel business cards instead of TM30 receipts for immigration purposes.
