As always, please take the following with a pinch of salt. It is a best effort, but the variables mean it can never be truly accurate and has wide error margins.
FY2016
EB1
Even though approvals look slightly lower at this stage, I expect EB1 to use its allocation, or close to it.
EB4
I-360 receipts and approvals have exploded, probably due to use of the SIJ subcategory by unaccompanied minors. Approvals in FY2015 were 26.4k compared to 16.9k in FY2014.
I don't expect any spare visas from EB4.
EB5
EB5-China remains retrogressed and the backlog is increasing, so no spare visas from EB5.
Family Based Visas from FY2015
The
published data suggests that there will be only a few spare FB visas available to EB in FY2016.
EB2
Worldwide
If EB2-ROW approvals continue at a steady state, then they could use c. 25k of their 29k allocation. EB2-M should give FA along with some from EB2-P.
India
From such a long way out, the prospects for FY2016 for EB2-I look moderate, depending on your point of view.
At this point, it looks as if EB2-I might have 10-11k total visas available. That would be in line with the July 2009 filing date accepted by USCIS for a couple of months at the beginning of the FY.
EB3
India
An excellent chance of FA to EB3-I in FY2016. I can see EB3-I progressing into 2006.
