I got my I-751 and N-400 interview as a dual interview.
My wife and I entered the interview office and 2 officers were there..One for the ROC and one for the Citizenship.
The oath happened immediately after the interviews and approval in the same office.
It was a long journey but finally I am a US Citizen. The sword of Damocles above my head is now gone. I feel a heavy weight lifted finally.
The officers were very nice and one of them is a Marvel/Back to the Future fan and has movie items on his wall. License plate from Back to the Future. Nameplate of the lawyers in Daredevil. So we had a nice chat about the movies and Marvel shows. He also has a picture of Grogu.
I hope that all of you will have a smooth interview as well and if ROC has not approved yet..expect dual interview.
