Why retrogression...Is EB3 to EB2 porting a real problem

[Raj0687]

Here is how to find the porting from eb3 to eb2, with respect to country India.

Federal year spill over = the total number of pending eb3s in Oct/current FY - pending eb3s in Oct/previous year - number of EB3 visas allocated per year.

For Instance consider India, for FY12 the total number of pending eb3s in Oct/11 - pending eb3s in Oct/12 - number of EB3 visas allocated per year.

FY12 = 51,758 - 47,354 - 2803 = 1601.

FY11 = 56,640 - 51,758 - 2803 = 2079.

FY10 = 60,874 - 56,640 - 2803 = 1431

These numbers per year doesn't seem to be big. On top of that USCIS said 19K eb2 spill visas issued to India. If that is the case the total number of pending eb2 should come down to 20k from 40K. What's going on here... you have any idea?
