Ok folks... I'll be mailing my application off this week, here's what I'll be including in the package...

Cover Letter
The I-751 Petition
Copy of my I-551 Green Card
Copy of the ID page of my passport
Copy of the K1 Visa page of my passport
Copy of both our driving licences - showing we live at the same address
Copy of our health insurance cards
Copy of my life insurance policy showing my wife as the beneficiary
2005 & 2006 Tax Returns
Copy of Target & Sam's Club store cards - both our names on the same account
Copy of our Visa Cards (3 in total) - all 3 show our names on the same account
Copy of a page from our Mortgage payment book & copy of some of the pages from the mortgage packet - showing we own the house we both live in.
Copy of our car insurance cards and our certificate for both cards
Copy of our car registration documents
Copy of bank statement pages from over the past 2 years
Copies of some Vetinary bills and receipts for our 3 dogs - both names and the address are definitely on that paperwork.
Some photos taken over the past 2 years
The fee (this part HURTS! )

Some questions I have...
All our utility bills - electricity, water, cable, house phone, cell phone - are in my wife's name only. Although I'm a registered name on the account, the bills only come addressed to the person whose name appears first. Should I include some anyway?

Also, the Visa cards are the same situation only with the names flipped. The bill comes addressed to me only, and my wife is an autorized user. Should I include these bills, or are copies of the cards enough?

Is there anything else I might be missing, or that might help?

Thanks in advance for your help!

It looks good. The only thing we added what affidavit letters from five friends about how they preceive our relationship

HI my friend and good luck , i think it s better to send them all copy of all the bills either under your name or your sposue name , the most important is to have the same adresse on them the office told me to send at least 5 bills or anything under my name as the same for my wife .so just send whatever u have so u don t get PRE your list look great i will do mine in march good luck
