a) Transformation Factor (TF)
The sum of factors that convert the raw PERM figures to the maximum number of I-485 applications that might be expected.
The factors taken into account are:
i) EB2%
ii) Approval rate at I-140
iii) Dependent ratio.
We all use slightly different figures. Currently, I use 65%, 80% & 2.05 which converts 1 PERM to 1.066 I-485.
b) Demand Destruction (DD)
Factors which might lower the numbers of I-485 calculated by the Transformation Factor.
These might be:
i) Multiple PERM
ii) Abandonment
etc.
In the tables I produced (what seems an age ago) I used 15% for PD2007 and 10% for PD2008. Those figures now seem somewhat optimistic, although I was also using an EB2% of 60%, which makes them slightly higher. The OR (see below) gave factors of 0.84 and 0.89 respectively.
c) Overall Ratio (OR)
The cumulative effect of Transformation Factor and Demand Destruction expressed as number of I-485 resulting per approved PERM.
Currently, I am using figures for DD of 40% for PD2007 and 35% for PD2008 to look at the low end of possible I-485 figures.
Based on the initial PERM numbers, this gives 1 PERM converts to 0.64 I-485 for PD 2007 and 0.69 I-485 for PD2008.
Even with those ratios, I get 40k potential EB2-IC I-485 for VB movement to date, including 250 Porting per month to the date the cases become ready for adjudication (2k total) and 1.5k cases from FY2011.
For an OR of about 0.8, which I have seen mentioned, the DD would need to be 25% for the TF factors I am using.
