I have received approval on my H1B petition on 30th April.I have not yet received I797.It has been 4 months.
My employer said they have already filled 2service requests but we have not received any Response.
Is this normal to have this much delay?
What should we do to inform USCIS?
Need help I am getting worried now,as my petition was for 2020 which took 1 year to approve and now this delay for i797
