I believe the BVA is adding an online option.
Hello, everyone, my case is almost finished, and I will give one final update once the Staatsangehörigkeitsausweis is issued. I was poking around the BVA’s German website when I found an option that allowed you to apply for Article 116, StAG 15, StAG 5, Feststellung, and renaturalization online! The only issue is that they seem to be requesting an eID (currently only available to EU citizens or those with a resident permit in an EU country, I believe). While this wouldn’t help the vast majority of us at this point in time, it still seems to be a step in the right direction. Hopefully, this will speed up the process and make documentation submission easier, but of course, all of that is to be determined. If anyone has any foresight on the matter, I would be very curious, as to my knowledge, the only application that could be submitted online was a request for a negative finding of German nationality.
