I think Phoenix is where we filed for my K1 visa in the first place almost 8 years ago (feels like another lifetime)
I filed for my N-400 online on January 19th, since it had been 4 years since I filed for my removal of conditions, and heard nothing back until now. Got my interview notice on February 13th. Interview was yesterday March 24th and just found out today my Oath Ceremony will be on April 17th, so will be going back to Louisville one last time.
Considering how long it was taking for the I-751, I was astonished at how quickly this all went for me. Almost 3 months from filing to the Oath Ceremony.
