So I have my Thai visa for tourism today with single entry. If I was to travel to Laos by land crossing border and come back into Thailand with land crossing border again, will I need to apply for a new visa or i can still use the same one i was issue today? Thanks in advance
TLDR : Answer Summary
A single-entry visa for Thailand is only valid for one entry. To keep your visa valid while traveling to Laos, you will need to obtain a re-entry permit before leaving Thailand, which costs 1000 baht for a single re-entry. Alternatively, you can reapply for a new visa at a Thai embassy or consulate in Laos.
