Been sick as a dog for nearly 3 weeks I have a non imm O visa, my 90 day report is in due in 2 days do I need to go back to Savannakhet Loas to report or can I go to my local immigration office. I was told by a local expat I can't do my first report on line. My Thai wife filled out her TM30 already. In Yasothon province. Thanks for any help

I am arriving in Thailand 4 April on a 60 day SETV.

I will be extending it for 30 days while there.

I will be in Yasothon Province the entire time.

Is there an Immigration office in Yasothon? the closest I can find is Roi et.

What documentation do I need to take to immigration for the extension?

I got my visa at Brisbane Consulate in Australia, based on a letter of invitation, I will be staying with a friend ( Thai National) at her house in Yasothon. Does she need to register me as a guest.

Do I need to bring the letter of invitation to immigration when I apply for the extension?

Is there anything else I need to know about?
