H1B expired without stamping - Same company. My options?

I got my H1B approved in Oct 2017 and it was expired in Oct 2020 without stamping.
I work for the same company that filed my H1B.

What should I do now?
Do I have to raise an extension?
This was expired at the time of Covid.

Note - I have a valid Business visa too and I have traveled to the US twice on that.
Please help me, Thanks in advance

Yes, your company can try to file for an extension using the same petition approval. This way you do not have to go through the lottery again.

I have a valid B1 & I got my H1B approved in Oct 2017 and it was expired in Oct 2020 without stamping.
I have traveled to the US twice on B1 in the past
My wife has a valid H1B (stamped) and ready to travel.

I would like to go to the US now along with her and work there, What should I do now? Please suggest the route

What should I do now?
Do I have to raise an extension or go there with business visa and try from there?

If you did not had H1B stamping done, then you did not had H1B status…So, it may be tricky. This is a grey area. If you had stamping, then would have been better. Now, there are some cases, that were successful, but some were not…
