From uk stamped in on visa exemption for 30 days. Already extended once for 30 additional days, which expires this week. I am due to fly back to work three days after it expires and don’t want to drive all the way to Mae Sai. I think I read that this extension can be extended for another 14 days at Chiang Mai Immigration. Is this correct?
TLDR : Answer Summary
The user inquired whether they could extend their 30-day visa exemption for an additional 14 days at Chiang Mai Immigration after already extending it once. Comments suggest that this is not correct, as only one extension of stay is allowed, and any further attempts might lead to a denial, with the possibility of being advised to do a border run instead.
