Interesting. We know a couple of Germans who have renounced German citizenship and obtained U.S. citizenship. I would think that people would choose dual citizenship whenever possible. But I believe the people we know plan to stay in the U.S., so they might have had different ideas. I agree with you that dual citizenship is almost always preferable, especially if one can maintain access to the benefits available in many European countries.
