Because in these type of cases generally there are no disputed facts, the whole lawsuit is a mere interpretation of the statues and federal regulations, there is no way that the parties can reach a resolution outside the court (of course, except the fortunate case when your name check is completed in the meantime and the case adjudicated by USCIS). For this reason the Joint Alternate Dispute Resolution Report should be very brief and simple and should state the above mentioned fact only. But because the name states: "joint" this means that both parties (you and AUSA) will need to sign it. Usually when Plaintiff is Pro Se, AUSA will write the required document because s/he is a law professional and s/he knows this better. In your particular case, when AUSA seems uncooperative, it may be possible that you will need to write this and send her to sign it and file it by yourself. You can ask directly her if she is going to write this report or you should do it. Because this is practically irrelevant in your case, I would not worry too much about the whole thing. Just make sure that even if she refuses completely to cooperate, you file in time a document stating the above mentioned facts and you should mention in that case that Defendants' counsel refused to cooperate with you, this is the reason that you submitted alone this document. If she continues to refuse to cooperate, you should send the draft of this joint report to her with certified mail and when you file your part of the report, you should attach as a proof the return receipt, showing that you tried to get her agreement but she refused to cooperate. I don't think that this ultimately will happen, because she is aware of the rules, which requires to cooperation between the parties, and if the judge sees that she refused even the most elementary cooperation, it will make her to look really bad.
