My Extension expires late November. If I get a new passport in the summer, can I wait until it's time to renew my Extension (late Oct) and then just present the new passport, or do I have to transfer the stamp before the Extension is renewed?
TLDR : Answer Summary
The question addresses the process of handling a Visa Extension in Thailand when receiving a new passport. The discussion indicates that upon obtaining a new passport, the individual should receive a letter from their embassy to facilitate the transfer of the visa stamp. While some immigration offices may allow waiting until the next Extension renewal, it's advisable to handle the transfer beforehand, especially considering the 90-day reporting requirements.
