Can South African expats obtain a Non-B visa in Cambodia?

Usually the thai consulates in Lao are where S/A passport holders go to get visas for thailand. It seems every place else is hella hard on S/A passport holders getting visas.

Yes, but be aware: If the applicant is not a resident in Cambodia, the application will be subject to approval from Ministry of Foreign Affairs of Thailand, which may take up to one month. Therefore, the applicant is advised to apply for a visa at the Thai Embassy or Consulate-General in their home/residence country or at the designated Thai Embassy for faster consideration times. -Additional-documents-required-for-citizens-from-so.html
