I just went to the Immigration Office in Nakhon Si Thammarat, want to apply for Covid Visa Extension, they told me they require not only the booking confirmation but also the report from hotel in the check-in day that I really stay there. Is it really required? When I came to Thailand on a TR Visa, nobody needed any report from the hotel I booked.
I'm sorry if this question appeared here already. I couldn't find anything via my phone.
TLDR : Answer Summary
When applying for a Covid visa extension at the Immigration Office in Nakhon Si Thammarat, it is necessary to provide additional documentation beyond the booking confirmation. Specifically, the office requires the TM30 form that your hotel submitted upon your check-in, which confirms your stay at the hotel. If this form is not available, you may ask the hotel to provide an email or document they sent to immigration.
