I put my N-400 application in the mail on Nov 10th and subsequently took a break for about 4 weeks, hoping that INS would take some time to generate FP notice. To my surprise, I found FP notice in the mail when I came back from my vacation. The FP appointment was scheduled for Nov 30th. I missed that appointment already.
Has anyone else had similar experience? Can I just go to the service center with FP notice and evidence that I was out during that period?
