Wife got her Interview Letter .. but i did not

[ash1003]

Hi,

Me and my wife submitted N-400 on the same day, and we went to the figerprinting on the same day, but after a month or so she first got the Yellow letter, then she got the interview letter.. but there has not been any changes to my status.. still showing information about the FingerPrinting interview .. Status.

I called USCIS they also did not have any information.

Do i have to be worried..

Thanks for your time.

Regards.
Jay
