I was naturalized as a US citizen in Dec 2012. During my interview process with the officer, I was asked if I wanted to change my name (even though I had not indicated it on the N400). Thinking it would be an easy process, I dropped my middle name and added my husband's last name to my last name. The office made written notation on my application file. When I took the oath a week after the interview in a public ceremony, I just received my Naturalization certificate. No name change certificate was given. I now realize that I need this to surrender my Indian passport and get a visa for the same. How do I go about this? I need to travel on an urgent basis.
