Here what I got from Melanie, I hope that will helps
Below is the response from USCIS at this week’s meeting. There is a concern that although the IPC, which is the government’s working group responsible for recommending exemptions, has made and plans to make additional recommendations for exemptions,the Secretary of Homeland Security has taken a very long time to sign exemptions (and in fact there are several that are pending with her and have been for quite a while). We’re planning some events this fall to put some pressure on the Secretary so she signs the exemptions quickly, please stay in touch.
imeline: Does DHS believe that the timeframe previously announced for clearing all cases on hold as of May 2010 by the end of 2011 will be met?
v Yes. There have been 14,000 exemptions to date, and are currently approximately 4,000 cases on hold. The exemptions currently before the IPC should clear out the remainder of the cases.
