recently introduced immigration skill charge (ISC)

[happypie]

I am really confused with recently introduced immigration skill charge (ISC).
From gov website, ISC is applicable even in Tier 2 general extension/employer switch:
https://www.gov.uk/uk-visa-sponsorship- ... lls-charge

When you don’t need to pay
You won’t pay the immigration skills charge if the worker you’re sponsoring:

has a Tier 4 (Student) visa and is switching to a Tier 2 (General) visa
has a Tier 2 (Intra-company Transfer) Graduate Trainee visa
will do a job with a PhD-level standard occupational classification (SOC) code
You won’t need to pay the charge for any of the worker’s dependants, for example their partner or child.

However at other places, it's not applicable for above mentioned situation:
https://netlawmedia.com/news/legal-law- ... pril-2017/

Non-EEA workers sponsored in Tier 2 before 6th April 2017, who wish to extend their visa with the same or a different sponsor;

One of my friend's friend recently got COS for tier 2 general extension (after 6th april) and his employer didn't had to pay.
However one of my other contact is saying that his employer has paid for ISC (his is also tier 2 extension but employer switch).

Does anyone have more clarity on this?
Thanks.

It's only for new visa applications, not to extensions or switching of employers who held leave before 6th April.
