I think you are confusing nomination and approval. Nomination is when you accept the offer and then the process starts and then after all checks and processing you get approved and gets approval letter.I am guessing the process/document is different in EE and non EE.
Has anyone with EE and PNP received the documents for Nomination Approval & Confirmation of Nomination in email or in gckey portal from their province of nomination?
Getting nominated is entirely different from getting approved.
Hope this helps.
