Bit of a different question…
My wife (Tha and UK passport holder) id flying with me to Thailand for two months.
When we return, she is going back to Thailand two weeks later with her daughter.
Is this too short a time for to return to Thailand on a second visa exempt?
My wife does have a Thai passport also. But need to know as the flight has to be booked with correct name in the passport.
