Udon Thani Immigration: For those who are on tourist visa or visa exempt and considering a 60-day covid19 extension, this office requires 30-day rental lease, and/or title book and owner ID to issue an extension. This is in stark contrast with the Bangkok immigration that did not even ask a Tm30 for my 60-day covid19 extension two months ago. It looks like small immigration centers is not the way to go for covid19 extensions. I had similar issues at Surin immigration as well.
