I thought it might be useful for people to see the highest number of EB2-I Trackitt approvals for a single month from FY2010 - FY2012.
The numbers are cases eventually updated in the I-485 Tracker over time (not only on the day of approval) for Primary applicants.
FY2012
February - 433 -- c. 5.8k
March ---- 503 -- c. 6.8k
FY2011
June ----- 280 -- c. 5.7k
July ----- 376 -- c. 7.7k
FY2010
July ----- 432 -- c. 6.3k
August --- 402 -- c. 5.9k
% change, so the Trackitt number for the same actual number can vary from year to year.
