A friend referred me to Petra Korn for assistance with the German certification for Dual Citizenship (Beibehaltungsantrag). I had heard from others who went through the process by themselves that it was arduous, time consuming and expensive but not always a sure thing to get approved. I wanted to make sure my request would get approved with the German government. My friend said with Petra's help he got approved immediately. I hired her and working with Petra was a pleasure. She made the whole process easy and she assisted all the way. With her knowledge and expertise we successfully submitted my paperwork with proper and convincing arguments. My request was approved by the German government without any further follow up. Petra is professional, efficient and very customer oriented. I recommend her without hesitation.
