Exactly. Can download Form TM47 and fill it in before you go. Otherwise, get one at the immigration office and fill it in whilst there. Sometimes they will fill out your TM47 for you. I give them a 100 baht tip for doing that. If they say “you’re missing something” it could be true or they could be holding out for a bribe. 500 baht would save you having to go away and come back.
