Department of State Publication 9514, CA/VO: October 9, 2012
For India, EB2 date will not be moved at least till April 2013. This is the agenda of USCIS to make money.
There are 45 thousand applicants who are on EAD now. Most of them have to renew their EAD/AP by Mar/Apr 2013.
If USCIS waits till they renew their EAD/AP, they can make around 40+ millions. This is the first benefit to US govt.
It creates some employments also in Attorney offices. That is the second benefit for US economy !
