gaurav:My take on your questions...
(1) Under EB2 there are not tons yet.( actually, at the moment, they have less number of 485s in kitty than available visas for the rest of the year.)
(2) Same explanation as above applies here'
(3) Common adjectives used for porting are High, Extremely high, unbelievable high etc...
These are "relative" in perception. For CO, 6k or 7k of porting could be extremely high, since it covers 2-4 years of EB2I. For us(poor us), 6k to 7k( even 9k) is not much( at least we prepped ourselves that way)
The point I want to drive is, depending upon where you sit in the auditorium the view of hot heroine differs here:)
Demand Data looks great :)
As per our calculations, hence our predictions might be closer to the actual... let's see.
