My child has dual US and German citizenship, we live in the US. Her US passport expired, the German one is still valid. Her new passport might not be ready in time for our travel plans. Judging from other answers on this site, we shouldn't have a problem leaving the US without her US passport, but coming back might be an issue. Is it possible to have the new US passport sent to Germany (I could pick it up at the consulate)? Or do I have to find a way to have someone else send the passport to Germany, or bring it there?
In case anyone else ever has this sort of problem, here's what happened: The National Passport Center in Portsmouth managed to produce a passport for my kid in less than 24 hours, I could pick it up the next day. They were also the friendliest government bureaucracy people I have ever dealt with anywhere. I asked them if they would have sent it to the consulate in Frankfurt if it wouldn't have been fast enough, but they said they don't do that.
