Has anyone found a visa service that helps with DTV extension in Chiang Mai? I used The Colonel for help with a residency permit but they don't help with the DTV extensions. After what I have read about trouble getting extensions at CM IO, I've decided to just use CM Border run service as they have been very good the 2 times I've used them and the process was predictable! If a visa service is available that can do it reliably and drama free that would be a good option. Thanks! :)
