It is better if the attorney does it, but if
the attorney is unwilling, then applicants can do it themselves.
I have done it and even got a reply from CSC by fax (Please always give a fax number for CSC to reply to).
I got a reply when I faxed to 949-384-3050 Div I. This is contrary to what the official document says (Div IV and some other phone number)
Good Luck.
