Is there an English word for "awaiting approval"?

Solution 1:

You could try "pending", as in "pending approval".

pending

  1. Not yet decided or settled; awaiting conclusion or confirmation.

Solution 2:

You don't await for something, you just await it (see green line below).

I don't see anything wrong with awaiting approval in a general sense, though, as suggested above (and in NGrams), pending does seem the most appropriate.

"Google NGrams plot of "Pending approval" marginally leading "awaiting approval" with no results for "awaiting for approval" (see comment).
