Austrian citizen here with a passport which I got from the Austrian Embassy in Bangkok applying in Jakarta for DTV.
Muay Thai DTV boss didn't have such a case, but would probably write the full name of the authority:
OESTERREICHISCHE BOTSCHAFT BANGKOK
Other options would be:
Austria
OEB Bangkok
TLDR : Answer Summary
An Austrian citizen applying for a DTV visa in Jakarta needs clarification on what to write for the 'place of issue' on their application. Suggestions vary, with some advocating writing exactly what is stated on the passport, such as 'OESTERREICHISCHE BOTSCHAFT BANGKOK', while others recommend simply stating the country, 'Austria'. This has led to a debate within the comments about the correct approach to avoid visa application cancellations.
