Petitions by U.S. citizens for their immediate relatives (spouses, children and parents) are generally adjudicated within one year. If your petition has not been approved after 2 years, you need to make inquiries to CIS. Using the number on your I-979C Notice of Action, you should inquire from the USCIS web site, the status of your petition. Also, confirm that you did not change your address.
