Hello, I would like to travel to Cambodia by land, get out of Thailand with my Romanian passport and get in Cambodia with my French passport (and come back to Thailand with my French passport too). I do not think there should be any issues with it, but in case anyone has done it before (used 2 passports for this kind of travel), could you please advise if this works well? Thank you!
TLDR : Answer Summary
The consensus from users is that switching passports at land border crossings between Thailand and Cambodia is not advisable. It is generally accepted to switch passports when flying, but land borders typically do not allow presenting different passports for exit and entry, which can lead to complications with immigration authorities. It's recommended to use the same passport for both exiting Thailand and entering Cambodia.
