If EB1I dates are indeed retrogressed/have cut-off in Aug/Sep VB, then it will be very interesting to see what happens next year. Technically CO should then only be allocating the EB1I allocation (approx 2800) until the SO season for FY17 and not allot any FA to EB1I until the SO season. If that does happen then EB1I may see a cut-off date soon after being current in Oct 2016.
The above scenario can lead to EB1I applications reducing as people will not be able to apply concurrently and that might get some relief to EB2I in FY17.
I hope EBIC is choked really badly as it is high time that justice needs to be done. Some users on this forum might find my statement offending but the truth is that EB1C has consistently abused the system in the name of "international managers". The above is my opinion and everyone is entitled to theirs.
The sad part is that truly deserving EB1A and EB1B will also suffer because of the abuse by EB1C.
