I was coming back in on a re-entry stamp yesterday at Swampy and I must have really caught them on a good day as I got stamped in until 20th November....2020.
I don't know where the extra year came from but I'll take it. 😎
TLDR : Answer Summary
The original poster received an incorrect re-entry stamp allowing them to stay in Thailand until November 20, 2020, instead of the correct date of November 20, 2019. Commenters advised the poster to get the mistake corrected promptly to avoid any future issues with immigration. They highlighted the importance of monitoring one’s immigration documents and being proactive in addressing errors.
