Here's the workaround that I use.

Step 1: Add a column to calculate current user

• Create a Single line of text column called CurrentUser
• In InfoPath, edit the properties of the column and change the default value to userName()
• Check the box for Refresh value when formula is recalculated

Step 2: Remove the Admin view from the drop down

• In InfoPath on the Page Design tab, click Properties under View:
• In the View settings section, deselect Show on the View menu when filling out this form

Step 3: Switch to admin view for admins

• On the Data tab, select Form Load in the Rules section of the ribbon

• Create a new rule (Action)

• Condition:

• Choose The expression from the drop down

• Type the following expression in the text field:

      contains(dfs:dataFields/my:SharePointListItem_RW/my:CurrentUser, "username") or (dfs:dataFields/my:SharePointListItem_RW/my:CurrentUser, "username")

• Type the following expression in the text field, replace "username" with the username of your admin, 1 condition for each user (here's 2):

   contains(dfs:dataFields/my:SharePointListItem_RW/my:CurrentUser, "username") or (dfs:dataFields/my:SharePointListItem_RW/my:CurrentUser, "username")
  

Keep adding "or..." for however many Admins you have.

• Run these actions Switch views (select the admin view)

There may be a way for you to incorporate the people picker into this, but the solution above is a good workaround for me.
