How can I apply for a 1-year extension after my student visa expires in Thailand?

To apply for a 1-year extension of your visa after your student visa expires in Thailand, you typically need to be enrolled in a university class and graduate with a degree. Extensions are generally not available for private schools or language classes. Upon graduation from higher education, you can apply for an additional yearly extension at the immigration office and may also switch to a NON-B visa if you secure a job.
