That’s the current document from Koh Samui immigration in Maenam. Unless there’s been changes in the last week or so they do not ask for a signature from the hotel.
Incidentally, and staying on topic, the schools lawyer presented everything I had (I let her ‘carry on’ when she said that she could do it) to immigration (all docs, seasoned funds etc). She’s returned from immigration saying that if The school meets the minimum monthly wage combined with the funds, that she/they can do it.. asked them for a slight raise and asked them to get on with it. One can hope.
