It's moving! FINALLY! (Advice for what to bring?)

[lilQueenP 15]

So the application is completed and they will email when the interview date is set. Since this application was sent June of 2013, what documentation of our relationship should we bring? here's what I had in mind:

chat logs for the past month or 2 (not all the conversations because that would be thousands of pages, but one snapshot every day or so).

two credit cards of mine were able to make him an authorized user without a SSN, so we'll bring those and the letters showing some financial dependency.

I'm on his work insurance in Haiti and have an insurance card with my name

proof of my name change

emails between myself and my apartment management showing our intent for him to live here when he comes

documentation of fertility care I am going through so that we can start a family once he gets here.

Anything else? This will be my 8th trip to see him and I already included boarding passes, passport stamps and photos. I've also sent 6 or 8 letters from others confirming their knowledge of and support for our relationship. And I sent phone logs and chat logs from the time of our application as well.
