I've got a multiple entry retired O visa. I entered Oct 11, 2019, so, 90 days is till Jan 11, 2020? If I plan to travel out of thailand on the 15th of January, do I pay penalty for 3 days past the 90day or we got a 7 day grace period past 90 days making it 97 days. What's the hard rule? Thank you for any reliable information. Cheers.
