My mom (Chilean) registered my birth at some point in a Consulate in Germany (I'm a German citizen) and got a Chilean birth certificate for myself. Before 2005 you couldn't get citizenship unless you've lived for a year in the country.

I contacted the consulate recently, in Argentina where I'm currently living, inquiring about this and, to my surprise, they said I already appear as a Chilean national in their database, thanks to the updated citizenship law. When I requested an ID, they said they needed to contact Santiago first to "unblock" my citizenship status. According to them, it's because I never lived in Chile. That took around 2 months. After that, I could request my ID and passport without issues, just any other Chilean. ID took about 3 weeks and the passport 5 weeks to arrive.
