Thank you for your reply.Is your D212 social visa a 1 year visa that is expiring on August 12? If so you probably have to apply for a new D212 visa or try to convert to a ITAS (KITAS).
I was in a similar situation with my D212 visa expiring in mid August. The immigration office only gave me 3 more weeks for my extension which was 7 week short of the D212 visa expiration. The immigration staff just said to keep doing extensions but I think that's bad advice considering my visa would expire. So I started D212 to KITAS conversion.
My D212 social, 1-year visa expires in January 2021. That's why I'm confused.
Maybe the local office had a mishap?
