How to Show or Hide Fields for administrative purposes

I am trying to create a form where one user fills out a portion of the information and then when they hit submit the email goes to an approver and they edit the form using the edit function and enter their approval information and then it gets submitted to another user who will process it.  The only thing is I do not want the approval fields to show when the initial user complete the form.  Its for a leave of absence form.  there are three parties involved:

User/Reuqestor

Manager 

Staff processor
