When I was staying at a friends place, I just took the form filled out and signed, a copy of his thai ID and house book signed and submitted them at immigration with no problems.
I’m not sure, but I’m actually gonna drive over to immigration and see if they can help get it working. Thanks I really don’t mind showing up for my 90 day report, it’s a good time to do some shopping and have some time in town. Problem is I don’t have my passport at the moment and I’m getting nervous because my 90 day is the 23rd. 😬
