What happens after I797-B Approval Expired?

Hello,

I’ve an approved I-797B H1B Document on dated 16th Dec 2016.

That document states the validity of this approval is from 01/10/2016 to 09/14/2019, means 3 years.

Now, I haven’t applied for DS-160 yet as my US employer told me to wait. The consultant company thru. which H1B had applied & approved is no more exists & I’m in touch with the immediate employer now.

So, my employer said that once the new IT setup will be live, we’ll directly apply for DS-160 without that consultant.

My question is, is my current H1B status still active because the end date is 14th Sep 2019.

If it is expired, then what should I do? Same question I have asked my employer & he said, we will sort it out.

What does it mean?

After the expiration, they need to again apply for something called as H1B extension with USCIS with the job they have for you in US. Once you have new H1B approval that is valid, then you go for H1B Visa Stamping by filling DS-160 form based on the new approval.
