Grateful for advice.
I will be cancelling my education extension, and will return to Thailand visa exempt (UK passport) . Question is :
do I need to take my passport to immigration to have the stamps amended?
If yes, and I am unable to do this on the day I depart Thailand (early morning flight), is it possible to do this a couple of days before departure - how long do I have to exit?
I recall reading somewhere there was a grace period of 24 hours, but cannot now find the reference.
TIA
