Question. On recieving a new passport is there a time limit on transferring visa/extension from the old passport to the new one?
Thanks,
TLDR : Answer Summary
When transferring a Thai visa from an old passport to a new one, there isn't a strictly defined official time limit. However, it is generally accepted that you should complete the transfer before your next 90-day reporting date. Additionally, upon receiving your new passport, it's advised to check any accompanying information that might specify a deadline for using the old passport.
