What are the procedures to transfer an educational visa to a new passport in Thailand?

The process for transferring your educational visa from an expiring passport to a new one in Thailand typically involves completing a transfer form. You may need to provide copies of your old passport, the relevant visa stamp, and your new passport. It's advisable to keep your old passport even if it gets invalidated, as some embassies, like the German one, allow this. In certain cases, like with the British Embassy, you will receive a letter to facilitate the transfer at immigration offices. Once you have your new passport, take both to immigration for the transfer, which is generally free.
