Wonderful Support for Renaturalization

Holger and his team provided excellent support throughout our citizenship process. After evaluating multiple firms for this family endeavor, we chose Siegwart and are confident we made the right decision. Holger and his team are well-versed in the German immigration authorities processes, and communi...cated efficiently to us throughout the process.

Excellent!!!!

I wish to thank Holger Siegwart with a difficult inheritance situation that we, as a family, were unable to resolve without his and his colleagues help. The untimely and tragic loss of our mother, Ute Staup, who wished to leave us her house in Bad Karlshafen to always cherish her memory and the wa...rm memories of our late grandparents, Walter and Helene Sippel. Mr. Sigwart approached our case with personal intrest, care and a genuine goal to help. He remained in contestant communication, was expertly organized and took on challenging moments with a sense of confidence and calm that resulted in the transfer of the property to us, the family, to keep as a treasure for years to come. I urge anyone with legal challenges such as ours to seek out Mr. Siegwart to deliver a complete result. My respect for Mr. Siegwart has no words to describe.

Relationship: Worked together on matter

"Mr. Siegwart is the attorney to call on for transnational legal issues involving US law, on one hand, and German/Austrian/Swiss law, on the other. I'm an attorney and I sought his advice on an issue that arose in a probate proceeding in Vienna. Austrian counsel was stuck on a choice of law issue, and Mr. Siegwart was familiar with the problem and gave us expert counsel on how to break the log jam we were facing."
