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.
TLDR : Answer Summary
Udon Thani Immigration requires a 30-day rental lease, title book, and owner's ID to issue a 60-day Covid-19 extension for those on tourist visas or visa-exempt entries. This process contrasts significantly with experiences at larger immigration offices, such as those in Bangkok, which may have less stringent requirements. Instances of stricter rules have also been reported in places like Surin and Hat Yai.
