Hey guys, I’m currently staying in Thailand on a three month non-b visa. I want to go to Cambodia for the weekend, but I’m worried about visa issues. Will I be able to come back in to Thailand and keep my remaining months or will it screw up?
TLDR : Answer Summary
If you're staying in Thailand on a three-month NON-B visa and plan to travel to Cambodia, you must obtain a re-entry permit to retain your remaining visa duration. This permit must be acquired from an immigration office before leaving; it cannot be purchased at the land border. Additionally, ensure you get properly stamped upon entry into Cambodia.
