I will have to agree with you Scapel. My wife hasn't ever gotten into trouble with the law, here or in her own country. But I'm still going to be on pins and needles until we hear some sort of answer. (Here's wishing it's a GOOD answer.)

I am going to post our attempted explanation letter we sent with the packet:
Dear USCIS examiner:
I am attempting to send this letter to explain why we are sending this I-751 Petition to Remove Conditions on Residence form outside of the required 90 day window prior to my wife’s (Name) Conditional Status expiring.
On July 7, 2007, we mailed the N-400 form and packet for Citizenship, but unfortunately, we had miscalculated the time line for submitting that package. We received the rejected package back on Nov. 10, 2007.
Then we submitted the I-90 for replacing the Permanent Resident card on Jan. 14, 2008. We received the receipt for the I-90 on Jan. 18, 2008. (Copy of receipt is provided.)
On Jan. 28, 2008 my wife received an appointment slip for a biometrics appointment for
Feb. 8, 2008. We were thinking she would be receiving the stamp to extend her Green Card at that time as that was the date her Green Card expires.
Upon going to that appointment we were informed we had filed the wrong form and to immediately submit the I-751 with this explanation letter attached.
Enclosed also please find the following documents to verify the times and forms we have submitted:
• Copy of the application N-900 with rejection stamp.
• Copy of the rejection letter from the N-400 packet.
• Copy of the web page receipt of e-submitting the I-90.
• Copy of the receipt and biometrics appointment slip for form I-90.
You may feel free to inquire at any of the sources of enclosed documentation for validity of their statements. Please advise me if you have any further questions or problems related to this petition.

Here's hoping this will be enough to allow them to proceed with this I-751. We were 3 day after the 90 days in which to file, so we'll see. (Man, there's a lot of paperwork to get together. Coordinating people to sign the affidavits was the worst.)
Wish us luck!
