After evaluating several firms, we chose Siegwart German American Law for my family's process for German citizenship. He and his team communicated clearly, laid out expectations for the process, and provided relevant guidance when needed. I would gladly recommend this firm for any citizenship or immigration matters.

I contacted Siegwart German American Law via their website and was pleasantly surprised to receive a call from Mr. Siegwart himself shortly thereafter. During our initial conversation, he gave me a thorough review of my situation and proposed a strategy with the greatest chance for the desired outcome. I found his fee arrangements to be fair and reasonable and decided to engage him. With his help and that of his legal assistant, Ms. Budimir, the matter was brought to a successful conclusion.

I retained Mr. Siegwart’s legal services to help with my application to retain my German citizenship (Beibehaltungsgenehmigung). He handled my case very professionally and cordially, patiently addressing many questions I had. He took the time to thoroughly understand my personal situation and speedily processed my case after I provided all the necessary data and documents. In result, my application to retain my German citizenship was approved by the German Bundesverwaltungsamt very speedily.

I checked out a few other lawyers first. I learned that Probate in Germany is very different. I hired Mr. Siegwart for this case because he actually practiced in Germany and the US. I am of German descent but do not speak the language well enough. Im glad Mr. Siegwart was able to reign in my hostile relatives overseas who thought I didnt deserve anything. I got my entire share without going to court. I liked the fact that I could actually get the attorney on the phone when I needed him.
