H1B Change of Staus

I am currently on L1 Visa. I have an approved H1B valid till 2023 but it is a consular application and not yet activated. I have the following queries

  1. Can my employer still apply for Change of Status?
  2. If they can, Can they also apply COS in premium processing?

@anil_am22 Can you please help with the above query?

You can apply COS in premium.
