Is there an English word for "awaiting approval"?
Solution 1:
You could try "pending", as in "pending approval".
pending
- 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.
