Apologies if this question has been asked many times.
I have family arriving from UK, they will travelling direct from Bangkok airport to Hua Hin and will be staying in my home for 2 weeks before returning to Bangkok hotel and return flight.
Do they need to file a TM30 at immigration
TIA
TLDR : Answer Summary
In Thailand, according to the TM30 regulation, any foreigner staying at a residence must be registered. While your family may not need to present a TM30 receipt unless they encounter immigration, it is recommended to register to avoid potential fines should any police checks occur.
