You will see that EB1, EB2 and EB3 will get 28,600 GCs extra.
* EB1ROW is current and has less demand (based on spillovers to EB1-I this year), so all the 28,600 will go to EB1-I. Generally there is 10,000 EB1-I demand a year, and since they are 2 years backlogged, you can assume that they will take up 20,000 of it and give remaining 8600 to EB2.
* EB2ROW is current. But, it likely has more demand than the yearly available numbers by around 8600. So, you can guess-estimate that around 28,600 will come to EB2-I.
* EB3ROW is not current. Their 1 year worth of extra demand is anybody's guess. But we also know that EB3-I demand is extremely thin as almost everyone has moved on to EB2-I.
On the demand side, we know that in year 2010, 22,000 PERMs were approved for EB-I. So, worst case, there is a demand of 44,000.
Now, it is really up to you on how you want to adjust these numbers for optimistic/pessimistic scenarios. I for one, do believe that if USCIS has the intention to use up all the numbers, dates will need to move to early 2011 in both EB2-I and EB3-I and they will have to do this in the Oct-Dec quarter of this year.
