Well, getting called in for an interview is generally a really good thing!
If you have already submitted all of your paperwork correctly, they are probably calling you in for your "final" interview where they make decision about granting a 2 year green card! Just be sure to bring lots of new photos, joint-account paperwork (if you have any more now) or any other proof of a bonifed marriage to the interview and that will help your case.
Good luck!
