Hi I need to join some Italian group to make an appointment for Italian embassy in bkk would anyone know what this group is thank you in advance

Hello! The research I did online says that once you get the proper paperwork from the place of study inside of Thailand for Ed visa that you have to apply outside of Thailand. So my question is for the people in Bangkok where do y’all go outside of Thailand to apply? Please be as detailed as you can…. The country, embassy, transportation there….etc. Thank you!! Any other info also welcomed!!
