Do I need to transfer my E Thai visa to a new passport?

When you receive a new passport, you typically need to have your E Thai visa associated with your old passport transferred. To do this, bring both your old and new passports, along with the visa printout, to an immigration office. There is usually a fee of 500 baht for the service. It's important to note that you cannot directly transfer the visa itself, but the entry stamp can be moved to your new passport.
