Wife had her Oath Ceremony on Friday in Baltimore. I wasn't able to go due to a conflict with work. The ceremony was scheduled for 9am. She said that they were about 60 people there that were taking the oath. As usual it started later then stated. When they checked her in they noticed she marked yes to travel outside the US since the interview, so they just asked what countries and how many days and had her initial what the officer wrote on her form. During check-in they handed her a packet with information, and they took both GC that she had (I told her to bring both her expired 2 year and 10 year card). After everyone checked-in an officer talked about culture. They took the oath, said the pledge of allegiance and saw a video from Obama welcoming them. After that they handed out the certificates and everyone was free to go. My wife called me at 10:30, so the entire process took a little over an hour.
Now we are trying to figure out how she is going to apply for her passport, since all of the Post Offices that offer Saturday Passport Service in the area require appointments and they are all booked for about a month.
