I'm so happy my mother moved with us to Thailand. She lived a happy life with us here for 15 years before passing away in August in her bed at home with me by her side. No challenge at all!
Once your passport expires, so does your visa. It's THB 500 fine per day up to 90 days. Maximum fine is THB 20 000. If you stay over 90 days you will get a year ban.
