On your Credentials page, if a credential is currently in a pending state (as shown below), this means that it's in our queue, waiting to be verified.
Verification can take up to a few business days, but you should generally back soon. You'll be notified via email when your credentials have either been successfully verified or rejected.
Having a pending document doesn't prevent you from receiving signing offers, so you can still receive and respond to signing offers if you have a pending credential.
