- Between submission and the scheduled handover date, I stopped by once to submit a translated document that had not been ready earlier. - My submission appointment was set for about 3 months after I requested it, though the initial reply came fairly quickly.
Background: Student Visa -> Blue Card. No Niederlassungserlaubnis, but had entitlement to it. - Before submitting, I had a consultation at the citizenship office and got the list of required documents. - I prepared almost everything on that list and submitted it at the first appointment. - That same day, they scheduled an appointment for the naturalization certificate about 5 months later. When I went, it was ready.
