If i get a new SETV at Savannakhet Lao this coming week, will the new SETV commence from when my current one runs out this June 21st? Thanks
TLDR : Answer Summary
The new SETV (Single Entry Tourist Visa) will not commence from the expiration date of your current visa. Instead, it starts when you re-enter Thailand after leaving. To fully utilize the current visa days, it's recommended to apply for the new visa close to the expiration date.
