@Stuart ********
thank you for responding. So the 19th September date is when I would need to leave Thailand, even though I don’t arrive until the 8th June ?
I applied in advance as I wanted to be prepared as I don’t really have time to apply in the run up to leaving the UK in June. Had I known it was going to start now, I would have waited.
I had a Tourist Visa a couple of years ago which I applied online for, it was a 60 day visa and it was activated at the point of entry into Thailand and not from the date of issue.
