Can someone 100%. verify that my friend can bounce just before the expiry date on his Non Imm O to stretch it out another 90 days? I know it can be done with a Non Imm B multi but just need to make sure he can do the same. We know he would have to bounce twice before the visa expiry date if he can stretch it. Thanks 🙂
TLDR : Answer Summary
Yes, your friend can extend his Non Imm O visa by exiting Thailand before the expiration date and re-entering. To secure an additional 90 days, he should ensure that he re-enters before the visa expires, and he may need to avoid border crossings like Aran or PoiPet that require an overnight stay outside Thailand.
