Add new comment to Naturalization process in Germany - What is your view

I can't say about Hamburg, but it Berlin it takes, listen carefully, around two years. You can forget about this expectation, it's unrealistic. Perhaps you could consult with your Ausländerbehörde or whatever it's called in Hamburg regarding an extension that does not cost that much, which is not unbefristet instead - just tell them that you started your naturalization and ask for their advice.
