FYI this is the website for the largest border bounce and visa run service company in Thailand...located in Bangkok. IF nothing else, Read their website for the latest news on the subject of border bounces or Thai Visa Runs.
You may have to show PROOF of your DTV Visa to airline staff on check-in for your flight ✈️ to Thailand...even to the connecting airline staff. Or to the land border crossing entry Thai Immigration Officer.
Upon arrival into Thailand, show the DTV visa to the Thai Immigration Officer and look at the STAMP placed in your passport to be sure you are STAMPED in for 180 days.
