Thank you Spec for the explanation. Now can you explain why EB3I demand have gone down by 2500 in 4 months period.
Since max available approved numbers will be 234*4 (EB3) + 234*4 (EB3 ported to EB2 before Sep 2004) = 1872
628 number is a big number for 4 months. (I'm not considering April'13 demand data after FBs numbers .)
Demand data till Jan 1 2007
-----Nov 2012-----March 2013
EB3----43500------41000 = 2500 reduction
EB2---- 1100------ 1650 = 550 addition
