Hi zlcjf, you can do a couple of things. Since 90 days are up since you applied you can go to the local USCIS office and ask them to issue a temporary EAD. Some offices know about it and some don't. My local USCIS office refused to isse the temp EAD but there does exists a standing instruction to all offices to issue temporary EAD.
Keep trying to contact the AUSA. The amount of cooperation depends on the district and circuit. If your district and circuit favors the Government then don't expect any help from him.
There's no need to think twice about including your current situation in your MTD. Stress that your EAD has expired, USCIS has not renewed it and if you have a family then say that your family is facing an uncertain future not because of any of your action but solely to an agency inaction. It is imperative to show harm to you and your family due to this inaction. If the only harm you show is "naturalization is delayed" courts may not be swayed.
Thanks. AGC4ME. I did all of above. I am in Baltimore, MD. The Baltimore office no longer issue interim EAD any more since Oct 2006.
It is true there is no mercy for Marylanders.
It is true that my family solely rely on my income. I have a one and a three year old. USCIS are just cold blooded.
