That's what i thought too. So, have you sent the documents by fax and the mail or just through the fax only? in my case, i have just sent the documents through the fax
If the question was for me, well one fax wasnt enough. I sent several faxes and mailed the actual letter certified. In addition I contacted my congressmen and one of those worked. Im not sure which one.
First, I sent a fax. I got an update, then after a month nothing happened. I called to see if NSC put my case in expedited processing and nothing, no record no knowledge. Then, is when I faxed my letter and support documents AGAIN, and repeated it 3 times in one week. I contacted my congressmen office and a week later I got a letter stating that my case was placed in expedite processing. 3 to 4 weeks later I got my RTD.
So its not easy to request an expedite processing for a RTD, unless you have a strong reason for either financial lose, work important matters, or CIS mistake, the petition will be denied. I have seen it many times in the place I volunteer.
If you do have a valid reason AND can prove it with documents, dont expect CIS to expedite your application with just one fax. Be proactive and fax your requets again, mail it, and contact your congressman office.
Or just wait and see what happens, hopefully NSC will do something.
