Hello All, I am in the same boat as everyone. I got my h1b extension approved on Feb 24th in PP (Nebraska Centre) with 1b1 classification. My employer or attorney have NOT contacted USCIS yet, I was told by the employer that the attorney told him to wait for some time (?) as uscis is issuing the corrected approval notices. Also When I checked my status today, the case has been re-approved (the approved date has changed from Feb 24 to March 10) and it said that they are mailing the approval notice. USCIS is resending my notice hopefully. Please let all of us know if you have any updates.
