Much Mann you are correct. The inventory also includes FSW 13 applications since it says MI3+ but that's FSW 13 applications that they had received as at October 8 last year.
Phunrae, all pending inventory is eligible for the 1400 target for 2014 and thats including all pre Fsw13 applications. Also, I believe Accra must have settled some cases and issued Visas between October and December 2013 and Visas that were issued between that period would have been issued under their 2013 Operational Target and won't deplete the latest 1400 target for 2014. Obviously, they have also received additional FSW 13 cases since after October 13 so I think the total inventory as at today really won't be much different from what it was in October 13.
My concern now is how they calculate their operating year. Is it a straight January to December cycle or something else? I know I've read in one of the forums where someone said its a March to February cycle. I cant confirm this but if its March to February, it means all Visas issued up until February 2014 should fall under the 2013 Operational Target.
