The embassy was open today and processing applications. May 1 is only a holiday for labourers in Thailand and not government employees. Source, my Thai girlfriend who is a government employee.
It's so disheartening for me also. It's good to see they are still processing visas however and I'm not giving up that an approval is coming this evening by 8pm. All day I've been in my hotel room waiting.
waiting too! The only thing I can think of is they are doing their DTVs in batches and I'm hoping we all get ours approved at the same time (my guess is that they have to use an external department to create the actual digital visa document and they create these in batches OR a high ranking official signs off on them in batches).
