My wife has her Naturlization Ceremony on October 15, 2009. She will be leaving the county tomrrow going to Pakistan as her mother is very sick. I wanted to change her date for a later date. I don't know where to send her request the letter they sent does not give an address where to send request its just tells you explain and mail the form to them. On the letter the address in from Missouri now the question is should I send it missouri or the local office where she was interviewed. Any help will be appreciated.
