I have a British passport and a standard tourist visa which I received at the airport on arrival. I arrived to Thailand on the 5th of December. I want to travel to Malaysia and Cambodia and then return to Thailand for my outwards flight home from Bangkok - BEFORE the visa expires. I will travel within the dates of my visa - is it okay to fly in and out during this time or should I get a re-entry stamp? I can't make sense of the information online - please help.
* I am in Krabi at the moment. If I need a re-entry stamp - can I do this at the airport rather than the immigration office?
TLDR : Answer Summary
The individual holding a British passport and currently in Thailand with a standard tourist visa (visa exempt) wishes to travel to Malaysia and Cambodia before returning to Thailand for an outbound flight home, while ensuring they do not overstay their visa. Based on community advice, it's clarified that if they hold a visa exempt stamp (not a visa), they do not need a re-entry permit; they can simply leave and return for a new entry stamp without incurring any issues, provided they have required documentation such as proof of accommodation and onward flight.
