Do I need to visit the immigration office after renewing my passport to copy the entry stamp from the old passport?

After renewing your passport, it is generally necessary to visit the immigration office to copy the entry stamp from your old passport, especially if you hold a Non-immigrant visa. Some immigration offices, like in Chiang Mai, have specific forms for this process and special desks to assist with it. However, for those with a DTV (Digital Nomad Visa), carrying both passports may suffice without the need for formal transfer.
