Stay away from this lawyer!!! We hired him to handle double citizenship. Very responsive before payment, but after he send the initial application we didn’t hear back for a year, despite us following up again and again asking for an update. Emails were read, but never responded. Now further clarifications are required for this initial application by the German government. Same thing, no response, despite reading all the emails. We now hired another lawyer. Do yourself a favor and stay away. There is whole bunch of other clients with the same experience.
