Firstly, an apology if this topic has already been covered but the laws governing it change fairly frequently.

I have dual nationality and 2 passports. I have been staying in Thailand for the past year on one passport but would like to change to my other passport. 2 possibilities: by land or by air.

Has anybody in the same situation 'swapped' passports at a Thai border? (i.e. left Thailand on one passport and entered a neighbouring country on another - after showing the exit stamps on the first passport). Is it possible to do this by flying into a neighbouring country / or back into Thailand and presenting the 'second' passport? Some countries will allow this but others will not so I'd appreciate hearing from anybody who has experience in Thailand and neighbouring countries.

It's rarely an issue swapping passports in the air.

Land borders are problematic as each side want to see the exit stamps from the other.

This can be done.

This can be done.

I suppose you should tell us which land borders permit a passport swap.

I was referring to the OP's reference to flying into another country.

Many thanks for the replies - they've been very helpful.
