The first phrase is not usable. The second could be, if incorporated within a sentence.
"It is not approved yet" is a correct sentence.

NOT A TEACHER!

I tried to make sense of "not approve yet," but I cannot come up with one idea!
I heard that you cannot use "present tense" if you use "yet."

However, I can see many usages for "not approved yet."
