I would like to know is it easier to get my passport renewed in Germany, I haven't lived there in 30 years, or here in the states. I still have my Mother and Brother in Germany. Also How would I get a temp passport to go to Germany.

If you are a U.S. citizen, then you must use a U.S. Passport.

If you are still a citizen of Germany, contact a German Embassy for information on renewing your German Passport.
