it’s was just one of the boxes to tick in their application form, they didn’t mention it specifically. And I never heard before that it’s a requirement for Ed visa. Just thought it was strange and wanted som clarification, thanks 🙏
Could depend on which agency you use, but if use “friendly Thai visa service” they have a deal with immigration at certain borders and can guarantee that you will get your 60 days stamp. I used them 3 times already this year. They check your passport before departure and won’t bring you if they can’t guarantee success.
