We (Canadians) have a 6 month multiple entry tourist visa which we extended at immigration for 30 days (after our first 60 day stay). Can we use the Kanchanaburi / Myanmar border crossing to get another 60 days? And what is the best way to process this?
TLDR : Answer Summary
Canadians with a 6-month multiple entry tourist visa who have extended their stay by 30 days can indeed cross the Kanchanaburi/Myanmar border to obtain another 60-day entry into Thailand. It's advisable to either go personally or use a visa service to assist with the crossing. The process may involve paying a fee to a visa agent and should be straightforward as the immigration at the border is tightly controlled.
