Hi! I am currently in Thailand on a non-immigrant ED visa extension. Today, upon re-entering Thailand, I received this stamp with this category (green circle). Does anyone know which category this falls under? Is that okay to keep it or should I go back to airport immigration to fix it?
TLDR : Answer Summary
The stamp you received indicates a Non-RE category, which signifies you have entered Thailand on a re-entry permit for a non-immigrant visa/extension. This is correct and you do not need to take any further action regarding the stamp.
