My personsl experience.

OK just flew in on 60 day visa exemption.

The landing card completed fine.

I was questions by the IO on how long I was staying.

They asked where I was going and I presented an invitation letter from my fiance detailing where i would stay and scans of her address book and her identity card. They gave a little nod and finally checked where I was staying that night before my flight to phangan in the morning. Then stamped it.

Overall about 3 minutes, but I believe facilitated by clear paperwork.

The adage better to have it and not need it than need it and not have it.

Fir reference I spent 39 days in September to October 2024. And 30 days February to March 2025 before this trip on may 15th.

I have a 52 day trip planned for September but I am going to apply for a proper tourist visa as it may save hassle with visa exemptions

I am currently in Koh Lanta with an under consideration stamp from MTT, do I have to go back to BKK to close or can I get done in Krabi any advice would be helpful
