So far I have:

-Letter from my work stating that my husband is the beneficiary of my life insurance
-copy of the deed to our house which we bought together
-letter from the bank stating we have 2 joint accounts and they have been active since May 2006
-letter from credit union stating we bought a car together
- copy of our ultrasound pictures ( I am 20 weeks pregnant)

Do I need to include pictures....I have never been one to take many....
Should I get a letter from our pastor or my husbands boss... my husband files self employed so we do not have joint tax returns.

Any help would be appreciated....we are ready to get this over with.

Include copies of your income taxes showing married, filing separately and showing the same address; show copies of the bank statements showing activity on the accounts by both of you (if you both use it); copy of car registration showing both names; copy of car insurance for both names; driver's licenses for both showing same address; copy of any health insurance that you have showing either of you as a beneficiary on the other's account or at least listing the other as spouse/emergency contact; copies of any utility bills in both your names showing the same address; copies of your wills naming each other as spouse/executor/beneficiary; copies of any joint travel you have done showing both names traveling together, any joint memberships (AAA, gym, Costco, Church, etc.), things like that. What you have now is good but isn't enough. You also need to show evidence that covers the whole time of your marriage so bank statements/ utility statements/ etc. from the beginning, middle and most recent date of your marriage are important. You don't need to include pictures, and letters from friends, associates, etc. are considered of secondary importance.

Good luck - and Congratulations.

and remember not all the evidence has to be joint.. if you have bills etc. that are just in your name and some just in your spouses name include those too.. they would show that you live at the same address...

just to give you an idea this is what we included in our package ....

copy of baby's hospital certificate
copy of baby's death certificate
copy of rental agreement
copy of car insurance
copy of one recent joint tax form
copy of 401K that states that I am the primary beneficiary
copy of health care statement showing that I am covered under hubby's health care insurance
copy of one recent gas bill
copy of one recent phone bill
copy of one recent cable bill
copy of recent bank statements
copy of paper showing that hubby added me to his bank account
Copy of some bills (Sirius, Netflix etc) with just hubby's name and our address on it
Copy of some bills with just my name on it and our address (recent electric bill etc..)
Some envelopes with both our names and address on them...

I just sent in the most recent bill for each utility.... The phone and gas were in my name but I added hubby's name, the electric company didn't let me add my hubby's name...... and I just included the most recent bank statement.... and the application that we filled out to add me to hubby's account...

This is what we had in our package (well....if I remember correctly)
title to the car (if it is in both names)
state ID or DL showing same address
credit card showing joint account
car insurance showing both name as insured parties
health insurance covering both of us (from my & his work)
401k & Roth IRA showing the spouse is beneficiary
letter & invitation sent to either or both of you showing same address
bills showing same address
affidavit from his mom & dad
boarding pass & pictures from vacation in July 07
joint tax returns (ours was from 2005 & 2006)
joint bank account statement (3 statements covering Jun 06, Feb 07, and Oct 07)

Good luck!
