when i got my new passport last year i took the old passport with my new passport to the immigration office and supposedly they transferred everything over to the new passport stamps and my tm6 with my old passport number, waited 2 days then picked up both passports ,but they never put it in the system because i never left the country, i can't believe this. but it is what it is!๐!
TLDR : Answer Summary
The user experienced an issue where their old passport's information was not updated in the Thai immigration system after renewing their passport, despite having submitted both passports to the immigration office. This has caused confusion and concern.
