Hi
Im new to this forum but im checking it quite often.
Im in the process of removing conditions. I almost have all package ready to sent.
Here's the list of things I sent for the I-751:

Copy of my conditional green card and my passport
Affidavit from 3 friends
Copy of life insurance policy where my wife is the beneficiary
Copy of joint checking account bank statements
Copies of our utilities bills: cable, power, water
Copies of our family plan cell phone bills.
Copy of my car insurance policy showing my wife as a beneficiary.
4 pictures as a couple taken and from her son's birthday
Few cards form our friends (anniversary)
Copy of furniture bills on both names.
Copy of our flight recipe to Europe for coming summer.

I don't know if its enough. I don't know what else i could submitted. For more then 2 years we lived in my mother in law house. We didn't take any loans, we both have very weak credit history. Any advises ??
Thanks

How about copies of your income tax forms showing that you filed as a married couple?
Honestly, it looks like sufficient evidence to me, I wouldn't worry too much.
Good Luck! Hope it's a speedy process for you!

copy of passport? I didn't know you'd need to submit that...

Thanks a lot
Yes i have copies of our taxes too.

Anything else, should we write a letter with explanation that we lived with my wife's mom till we moved to our place???
We still didnt change our ID's??
What do you think guys??
Im worried because our package is not as big like most of couples here:(
Thanks again for all response.

I probably would add these things if you have them:
Lease/mortgage of the place where you live
Tax information
DMV registration for the car
Drivers licenses for both of you showing the same address

Good luck!

How about copy of hte marriage certificate????

Why, this isn't required in the directions?
