Thanks. I remember reading that it wasn't required in my case. But not everyone agrees. My landlord just messaged me that he will check. I have feeling it comes down to the luck of the draw.
I live in BKK and I stayed at Amara Resort for one night. My landlord is in Isan and has a good relationship with the local Thai Immigration office. I thought I read where the TM 30 requirements had loosened a bit. I also messaged him, and I'll post here what he says.
