Expect to be singled out as ANY foreigner (anybody not holding Thai or Laos passport) and asked medical questions, signing a medical declaration and having your temperature taken.
Employee at the consulate who was denying tourist visas and asking for COVID-19 certificates claimed there was a real risk of the Savanakhet border closing soon. We then asked the immigration officials attending the border post who said the border would never close. So I think even within different ministries there is still a lot of confusion and miscommunication about what’s to come.
The Thai consulate in Savanakhet is no longer issuing tourist visas and is demanding health certificates for many different countries. Things are changing by the hour it seems.
