Here's a tid bit from The Hill, a newspaper written for an widely read by congress.

"CIA agents work under different sorts of “cover.” There’s “official cover” — like when an agent is assigned to a U.S. embassy under the guise that he or she is a foreign service officer. Then there’s “nonofficial” cover — like when your business cards say you’re a manager at Acme Overseas Energy Corporation, but you really work for the CIA.

Plame is in that latter category."
