Much anticipated bulletin of the year is December 2007 visa bulletin (Exclude July bulletin fiasco)
considering no change in previous two bulletins (November and October) and during November time frame DOS might have finished receipting huge number of I485s filed during July-Aug this year.
We can guess that DOS will have all inputs from USCIS on visa demand and will have better idea of visa numbers required.
Hence December bulletin might have some news.
Is there a prediction on December’2007 visa dates?
Worst case — heavy retrogression , Dates for EB3 may move back to 1998.
Best case — Remains unchanged as November Bulletin.
The decmber’2007 bulletin has not been released as of writing this post.
