They asked me to provide a scan of my passport page with the Vietnam entry stamp and “Business registration and copy ID card of the signer.”
The Gym I am enrolled in is Tiger Eye in Bangkok.
They provided me with all the required documents after I enrolled.
I signed up for 1 month primarily but this can be extended. The month cost 12,305 Baht for unlimited classes.
The whole process was very easy and straightforward
