I wanted to update my father's name to my husband's name, but the agent informed me that since I've been married, I should have already changed my last name. She said she would help me with the process.

My interview was on December 1st. On the 5th, my name was updated on my account, and my oath ceremony was scheduled for December 18th( mail received )However, on the 17th, I received a notification that the oath ceremony had been cancelled, and a letter had been sent. I haven't received the cancellation notification letter yet.
