I am posting this for your reference.
EB1 140 at NSC
Received in May 2003
RFE in Nov 2003
Denied in Apr. 2004
Appealled in May 2004
Approved in Oct 2004
Recommendations:
Do try the appeal after denial, even though sometimes the chance seems really slim. Do quote the relevant laws and previous cases in the appeal.
I have to work on my I-485 now--another battle ahead waiting for me to fight.
Good luck to all the EB1-140 fighters!
