How long should Identity Validation take?

I was wondering if you could help me, I’ve been trying to get the Trusted Signing platform setup and running, but my Organization Identity Validation has been stuck in progress for over a week.

Would you be able to provide any insight into what might be holding the process up? We need to start signing our mobile applications and installers.

I did receive an email verification, and successfully verified my e-mail address, but after that nothing has changed.
