PTPA. Hi, I am currently in bangkok holding an ED visa under a thai language school. Recently, I got accepted in a University (kmutt) to study under a bachelor degree program with a scholarship. I asked my school if it's possible to change to new ED visa here in bangkok and they said 'yes'. I inquired about requirements needed, and they just asked me for a copy of my passport, the TM6, and cancellation letter from my thai school. I'd like to know what other documents I should have upon application so I could prepare. Thanks
