Hello, i am a Thai PR. I just got a new passport issued by my embassy in Bangkok. My Non-quota immigrant visa is still in cancelled old passport but valid for the next few months. Endorsement in the resident book also still valid for the next few months.
The question is, Can i leave Thailand and return using both passports together or do i need ask a new non-quota immigrant visa and endorsement? Or do i need to transfer Non-quota immigration visa to the new passport before leaving Thailand? If anyone had experience on this please advise. Thank you
