What you can settle without travelling
A good share of German paperwork never reaches a consular counter.
- Order copies of German civil records for a citizenship file: those come from German municipalities by post, and they are the slowest part of any descent case
- Order a German birth, marriage or death certificate: the registry office of the German town where it happened issues it, and most of them take an online or postal request
- Get a certificate of conduct: the Federal Office of Justice handles it; any US notary public can notarize your signature on the form
