I have single-entry ED-visa (student visa) that is valid for 90 days. How can i get one re-entry, if i make a trip to cambodia& vietnam ? From the immigration office or from the airport ?
TLDR : Answer Summary
To obtain a re-entry permit for your single-entry ED visa while traveling to Cambodia and Vietnam, you can request the permit either at the Thai Immigration office or at the airport. The cost is typically around 1000 Baht, though this can vary depending on the airport and any additional fees. Ensure that you return to Thailand before your visa expires, as re-entry permits do not allow entry after your official visa stamp has expired.
