We are now in the end game for FY2012, so here's some speculation for the numbers via back calculation.
EB1 appears to be heading for mid 30 thousands - let's call it 35k, which yields 6.5k spillover. EB1 usage may be slightly higher, but approvals seem to come in spurts on Trackitt.
EB5 appears to be heading for 6.2k according to CO, which yields 4k spillover.
The EB2 allocation of 41.5k plus the spillover above gives a total of 52k.
The EB2-WW share of that allocation is 35.5k. If we take the 8k backlog for EB2-WW that most people are talking about due to retrogression, then EB2-WW have used 27.5k of 52k.
That means EB2-IC have used 24.5k.
If EB4 contributes anything, it would both increase the total available to EB2 and the numbers used by EB2-IC.
Those numbers are surprisingly close to what I have calculated. I have EB2-WW at a slightly lower figure and EB2-IC at a slightly higher figure.
Directionally, I think the numbers are probably about right.
I think we are now starting to use the final month's worth of visas and expect them to run out in the first half of September, as they did last year.
Edit to add:
CO said previously in late February (in the
Alan Lee article) "
that he expected approximately 55,000 EB-2 numbers to be available for the year" (FY2012). I think this sets the upper bound of visas available to EB2. The number may have (and almost certainly have) subsequently reduced due to higher approvals elsewhere
It is possible that EB2-IC have already been given dome of the EB2-WW allocation and the figure is higher than that calculated above, but the limit to that increase would be 3k. That would also lower the number already consumed by EB2-WW and set the expected backlog in the 6-9k range.
The other alternative, already discussed above, is that CO is expecting up to 3k to be available form EB4.
