Jason Brennan asked in another topic:
Im on a single entry visa at the moment and im about to extend it for another 30 days..when that 30 days is up can i just do a border run and re enter again on visa on arrival for another 30 days or do i have to fly out off thailand??
TLDR : Answer Summary
The original poster inquires about the possibility of extending their stay in Thailand on a single entry visa and then executing a border run to re-enter on a visa on arrival. Community comments clarify the process of extending a tourist visa for an additional 30 days and highlight the limitations on border runs and visa types. It is noted that extensions and border runs are subject to specific immigration regulations, suggesting the necessity of knowing the visa type and passport nationality to provide a complete answer.
