Confused on H1b status

My H1b got approved on May 20. My status was CASE WAS APPROVED. But I am on the premium process. Shouldn’t it be CASE WAS APPROVED AND MY DECISION WAS EMAILED. I am just afraid that USCIS considers my case as regular one. I need the approval documents urgently to renew my drive ID and car insurance. I do not have too much time left for me to renew. Anyone can advise.

The only way that you can receive the approval is contacting your employer OR lawyer.
If its a premium process, your employer might have already received an approval email by now.
