Hello,
The consulate itself did not ask for other documents. We just had been preparing the interview for so long ( having a lawyer, reading many discussion boards...), that we knew " the more, the better".
Just take anything YOU think is relevant to your case:
I won as single, and got married. So we wanted to prove that it was a true relationship. We brought pictures with dates behind them, of family events, of travels we had done. We also had previous lease agreements.
The officer may or may not ask for US tax returns : you mentioned your husband is a student in the US. So, at least, he filed form 8843, and maybe also 1040NREZ if he had a US source of income ( is he a TA, a RA, fellowship award, any kind of US money?). In our case, the officer did not ask for it.
But if you have them, just bring them. Just to be safe, and not to regret.
You can ask for a tax transcript, it's free. (not a copy of your return, then it's $40).
We did not have an affidavit of support. We had more money than it was required, and both of us had job offers: we had graduated in May from a Master's degree, so it was pretty easy for us to get a job ( and we were already living in the US).
But I guess it's worth mentionning that we first showed the bank statement. But the officer specifically asked for more: that's when we showed our job offers.
In fact, the officer also evaluates your potential to find a job (not to become public charge): if you do not meet the requirements of the poverty guidelines, it can still be okay if you've got potential to find a job.
I guess if you have ALL the documents, you'll be fine ( if you meet ALL the requirements). The rules say that YOU are required to have at least a high school diploma ("bac"), but the truth is that it's better if both of you have one.
We were students in Massachusetts. ( so we chose Boston as our POE). Now we both work in Connecticut.
By the way, one of your previous posts : there are only a few french dv winners, because not too many french people initially play.
