Im currently in CM on a STV, due for the final visa extension next month. Its my understanding this is single entry, is there any way around this as I'd like to go away for 1 week without losing the remaining 3 month extension? Thanks.
TLDR : Answer Summary
The Special Tourist Visa (STV) is a single-entry visa, meaning that once you leave Thailand, you cannot return on the same visa. However, it may be possible to apply for a Single Re-Entry Permit at your local Immigration Office before leaving, which would allow you to keep your current extension valid. It is crucial to verify the rules with your local immigration authority regarding the ability to extend your STV after leaving Thailand.
