What is the process to re-enter Thailand on an ED visa after leaving the country on a single entry ED visa?

When leaving Thailand on a single entry Education (ED) visa, you will need to apply for a new ED visa before re-entering the country. This involves visiting a Thai embassy or consulate in your home country or a neighboring country, presenting the required documents, which typically include proof of enrollment in an educational institution, and submitting the visa application. After your new ED visa is granted, you can re-enter Thailand.
