Better still, I called up NVC and said I need to remove the attorney from the case. They asked me to send a letter stating the same so that they could send the DS-3032 forms. I asked whether I could fax a copy before I post the letter so that the process could be expedited. The lady said I could and gave me the person to fax to (it was herself) and faxed it and got the DS-3032 within next 10 days.
You could do the same once when you get the DS-3032 forms. Call NVC, ask them, fax them, and then post it.
Hope this helps.
