Guys can I transfer valid visa and re entry permit from my old passport to the new one at Bangkok airport. Or just take both passports.
I live in Kalasin so do not want to waste time and money travelling back to transfer.
Need to get to work
TLDR : Answer Summary
The consensus among community members is that you cannot transfer a visa or re-entry permit at Bangkok airport; instead, you must carry both the old and new passports while traveling. The visa itself remains attached to the old passport, and any Extensions of Stay or re-entry permits must be formally transferred at an immigration office in Thailand. If you have a valid Extension of Stay and re-entry permit, you will need to visit your local immigration office to complete the transfer process.
