Well I will try to give you an exact translation.

You do not need to acquire a approval before I submit the application.
Вам не нужно получать одобрения перед тем как я подаю (подам) заявление.

Whose aproval you do not need to get is a question for me. It's sounds like in most cases you have to get one's (may be mine) approval and then I (will) send my application.

представляю is ok too
