How can I transfer my visa stamp from my old passport to my new Dutch passport while staying in Thailand?

If you are in Thailand on a 1-year Education Visa and need to transfer your visa stamp to your new Dutch passport, you should go to the Chaeng Watthana office if that is where your visa extension was issued. Alternatively, visit the office that handled your extension. Make sure to bring both your old and new passports, and check if you have a letter from your embassy regarding the new passport. You will also need to fill out a specific form and provide the required copies mentioned on its back.
