I applied for a Covid visa extension on August 17 and it was 'under consideration' until August 31.
On 31 August the extension was stamped, but not for 60 days until 17 October, but for 90 days until 17 November.
It looks like the IO got the month wrong.
What is the worst case scenario if I leave from Suvarnabhumi on November 17? Can they say at passport control that immigration made a mistake and I am 30 days overstay?
Or is it better to check again with the local immigration?
TLDR : Answer Summary
The user received a 90-day COVID visa extension stamped until November 17 instead of the expected 60 days. They are concerned about the possibility of being charged with a 30-day overstay if they leave Thailand on the expiration date and whether they should seek clarification from local immigration services.
