no need to panic -- there might have just been a misfeed on the copier that page 2 got stuck on page 1 when you were making copies.
it wouldn't hurt to call them on monday and explain your situation. i'm sure they will give you some kind of advice on what to do or what to expect.
i'm not an expert, but i think there are a couple of scenarios that could happen:
1) CSC will issue you a NOA1 upon receipt of your application which extends the GC for 1 year. You will surely get an RFE for incomplete documentation.
2) CSC will return your whole package.
Since you stated that the GC doesn't expire for another month, i think you have enough time to make corrective action if scenario 2 happens.
Watch out for the check... if the check is cashed, NOA1 is on the way.

Sorry to hear that dude. Since you're GC is valid for another year or so, you can definitely stay here in the US. Once your window opens, file for ROC. But it's best to take that offer from her family and get their testimonies now -- you'll never know what happens once that divorce proceeding start, it might get ugly and her family may no longer extend that offer when you need it... Best of luck to you.

Oh great!!! thats a nice link....have you done this before? Thank you so much again!

Wow, your AOS journey is so quick! Good luck tomorrow!
