I am on a non imm O-A multi entry visa been here 4 weeks. My thai friends decided on a road trip to Cambodia is there anything I need to be aware of ? Will my 90 start again ? Anything I need other than passport ?.thanks in advance .
TLDR : Answer Summary
If you are traveling to Cambodia with a non-immigrant O-A multi-entry visa, be aware that your 90-day count will reset when you return to Thailand. You will need to report again 89 days from your new entry date. Ensure you also check visa requirements for Cambodia, as you may need to obtain a visa on arrival.
