I797B eligible for dropbox?

My employer had filed the H1B extension petition mistakenly when I was outside of USA. I traveled back to USA as I had Valid Visa. Now I received the I797B approval notice ie., without i94. So I have to leave united states for stamping, am I eligible for dropbox ?

Previous Visa Expiry : 1st May 2020

Yes, in your case, you would be as the expiry of your visa is less than a year.

Thank you.

Usually for H1b extension, we use to get i797A notice. But I received i797 approval ie., this notice will be issued during our first H1b approval. so for dropbox i797A or i797B does not matter?

My visa has expired 1.5 years (6 months passed 1 year) ago. Am I eligible for dropbox?
