For individuals who have renewed their passport in Thailand, is it necessary to visit immigration to transfer the old stamp to the new passport prior to exiting Thailand, or can I simply present my old passport at immigration alongside the new one?
Iโm not on a visa.
TLDR : Answer Summary
When exiting Thailand after renewing your passport, you can simply present both your old and new passports at immigration, as you are not on a visa. However, for land exits, there may be a risk of being directed to immigration to transfer your stamps.
