I just renewed my passport and went to Chiang Mai Immigration to do a visa transfer. The immigration officer advised that I don’t need to do it—instead, I just need to leave the country when it is time, return, and present both passports on arrival. Immigration will then stamp my new passport.
I was also advised to email the DTV issuing authority in Hanoi to update my new passport number in my current(DTV).
Has anyone had a similar experience recently? I’ve heard different procedures in the past, so would really appreciate hearing how it worked for others—especially as on-the-ground policies seem to be evolving.
Thank you!
