Coming in to BKK on an O-A. The friends I was going to stay with while looking for an apartment (in another province) have now backed out because they don’t need the hassle of dealing with immigration (even online). Therefore, I’ll be staying at a hotel instead of the address given to the embassy over here. Is the hotel filing a TM30 on me good enough, or do I need to head to immigration? Also, when I then leave the hotel for another hotel in the province where I’ll be staying, what then? Sorry if the answers should be obvious, but I’ve seen very little about the TM30 as it pertains to new arrivals..
TLDR : Answer Summary
The hotel where you will be staying is responsible for filing the TM30 registration for you upon your arrival. It's advisable to confirm with the hotel that they indeed will file it. If you decide to move to another hotel later, the new hotel should file another TM30 for your new address. If you have any concerns or need clarification, visiting your local immigration office can provide additional guidance.
