Switch from ICT T2 to T2 after new rule

[suryashmi]

1.I got my VISA (T2 ICT ES) on VISA it mentioned valid from 2nd june2010
then got extension till 2016 june
the ILR rule change affect from 6 april 2010?
so i am not illegible for ILR isn't it?, my visa was applied by my company, don't know which date.. they are saying 6th May
now my question is ..
is there a way to find out which date the company submitted the VISA application ?
if CoS is assigned in april, will that override the VISA Valid date , am i still illegible for ILR?
as per new Switching rule if i apply for T2G will i get 5 years extension ? my T2 ICT valid from june 2010 to june 2016
so i will get extension till 2020 ?
i can stay in UK for maximum of another 1 year even after switching from Tier 2 ICT visa to Tier 2 General visa. Could you please suggest me?.or i will get 5 years from the day od switch
